Air Pockets…They make the Difference

Rugby in the rain. We received about 8″ with this storm, completely welcomed after nearly 2 months of dry and warm weather.

ScannedImageThe other day, while standing in the long overdue rain, watching my son’s Rugby game, I was thinking about what makes my crochet hat and gloves warmer then my denim jeans. The answer is simple, but also kind of surprising; air. The more little pockets of air that are trapped next to the skin, the warmer you can stay.

The process used in twisting the yarn and creating little knots, creates little pockets that trap air. Depending on the yarn and stitch combination, different levels of warmth can be created; this is why lace can be warmer than expected. The more things are compressed and made tight and dense, does not necessarily create a warmer fabric as it can press the air out of the work.

This is true with the yarn as well. Often it is realized that wool is warmer then bamboo, this is because of the fibers that are used. Bamboo, even though it is a plant fiber, is processed and extruded in factories creating a long smooth yarn that absorbs moisture, and thus in hot weather will keep you cooler by wicking away perspiration and allowing it to be evaporated. While the animal fibers that are utilized in wool yarns, are created naturally to keep the animal warm and dry. This is done by the crimp of the fiber itself.

2 locks of wool, notice the crimp of the fiber

Wool fibers are not like hair, they are crimped (like the fashion in hairstyles from the 1980’s), it has stretch (like elastic) and it grows in clusters (a patch grows together and can be plucked out together as one group). This nature helps to create air pockets in the yarn that is being created (depending on the process used, more or less air can be trapped).

My single crochet ribbed hat over my denim pants

So while my woven denim might be durable it does not offer as much warmth because the amount of trapped air is limited. But that hat, made only out of single crochet ribbing and my gloves made from back loop single crochet kept me quite toasty in comparison.

Thoughts on the Thermal Stitch…

ScannedImageWhen I started out to write this post, I was thinking of the cold weather I was seeing on the news, and it made me think of the thermal stitch. I have always been a little intrigued with this stitch; it makes a double layer fabric and has the resemblance to long johns, with the little indented squares. But as I started writing, I realized that there were questions about the properties of this technique that I couldn’t quite answer. So that is how I will preface this post, that it is a little beginning exploration for me with this technique.

Insert hook from the bottom of the loop, beginning with the back loop from the row below (now facing) and the front loop of the stitch of the current row

Yarn over and pull through 2 loops

The basic premise of this stitch is that you work single crochet stitches in the front loops of the row as well as the back loops of the row below. Working the stitch into the foundation chain can be a little daunting, so to give you an understanding of the stitch I will begin on the second row of a piece of single crochet. The rows of single crochet will be offset from one another, this creates the setback, while pulling up the lo op from a row below creates the edges to the “indented little square”.

Yarn over and pull through remaining 2 loops to finish stitch

One of the main things to remember with this stitch is to insert the hook in the loop of the row below from the bottom, then insert it into the front loop of the next working row from the bottom.  You then yarn over and pull through both loops (you might want to pull up a longer than usual loop), yarn over again and pull through the two loops remaining on the hook to finish the stitch.  This will create a dense fabric, and if you want to have a little fun, you can alternate colors every row and get a double sided fabric (although there would be many ends to weave of leave it fringed).

Play swatch, showing same technique using sport weight yarn and an N size hook (in one color), look at the open effect…has some possibilities….

One of the areas I plan on playing with is large hooks with finer yarns. In the small sample I started working with I was impressed with the draping I received as well as the slight openness of the fabric (made me think of springtime). Amazing how attempting to explain a simple concept can yet lead to more questions, and hopefully better understanding…I will keep you posted.

Uncovering the Wool from Over My Eyes

ScannedImageI will admit, as a long time crocheter, I used acrylic yarns almost exclusively for years. I do not say this as a negative thing, acrylic yarns have many practical purposes and companies are creating new textures of yarn with them daily, but there are other practical mediums out there that deserve attention too. However there were several reasons for my long term use of acrylic.

First, availability. In years past I could actually pick up Super Saver in the grocery store while my mom got milk and eggs. Since it was already at hand it was easier to use more regularly. However times have changed, even finding the box stores with Super Saver are getting harder to locate (or involve quite a drive to get to). However box store yarns have become more diversified and I can find fibers that would have been seen only in small local yarn stores in the past.

Secondly, I knew how to use it. A pull skein is a simple concept that involves no extra work on my part. I could pick up a skein and a hook and go right to work, with a hank I was at a loss. I did not want to look like I was confused or unskilled, so I never really picked them up. I guess I figured that if the yarn could confuse me as to how to actually start using it, things would not go well. But after meeting some local spinners and learning how yarn is created at a wheel, I learned how to handle a hank (Here is a past post that shares the explanation).

Finally, thirdly, cost. I like to think of myself as spend conscience. I always looked at the cost per yard to find my best value (I admit I still am very aware of this even today). However, over the years I have come to realize that quality can make a really difference in my end product. Often the yarn can make or break a design. I use my Vineyard at Dawn Shawl (pattern in Spring 2013 Crochet! Magazine) as an example (created with a Blue Heron Rayon/Metallic), it has great drape, and is just striking, but if it were worked up in a chunky yarn it would have a very different effect, imagine it in soft, fuzzy mohair, which would be a different effect as well.

So, while these three obstacle where in place, I never tried luxury yarns or even wools for that matter until the last decade or so. When I first attempted wools, using my value shopping method, I found fibers that were not the most ideal. It worked up like I expected wool to, scratchy, itchy, and somewhat stiff. It played into all my negative preconceptions, but the more I learn out fiber the more I realized that not all wool is created equal.

Basically saying “wool”, is like saying bouquet, while terms like Merino, Shetland, and Romney are names of the flowers. These “flowers” have different properties that offer a different quality to the yarn. They have different degrees of softness, of loftiness, of felting ability, of amount of twist in the end yarn, and of durability. I won’t pretend to be an expert in know all the differing qualities of wool breeds, but I do know that the differences are there and can really make a difference in the end quality of my work.  

New Born LambOne of the first grading areas is the diameter of the individual fiber. The smaller the measurement in microns the finer the yarn, for example Superfine Merino might have a range of 15.6-18.5 microns, while carpet wool can have a measurement of 35-45 microns. This is before they are spun into yarns, so basically the larger the individual fiber the courser it will be. This alone can create many differing yarns out of wool, but then there are other properties such as crimp and staple length that play into a yarns texture. So you cannot take the term “wool” on face value, different wool breeds react differently (even to felting, some felt very little and others felt just by looking at a washing machine). I guess like most of us, there is more than meets the eye.

My Color Change

ScannedImageSometimes what makes the biggest difference with the appearance of your work, are the things that it is assumed you know. For crochet this means those little things in a pattern that state; “weave in ends”, “change color”, “finish off”, “yarn over”, and the unwritten beginning slip knot.

These are areas that I have taken a little time and explored, to see what feels most comfortable to me. I have some past posts talking about weaving in ends and yarning over, so today I thought I would take a look at color changing.

Completing a stitch and working the next stitch in a new color

I have played with a couple different approaches to changing color since I started crocheting oh, so many years ago. I think in the beginning I just tied the colors together, sometimes at the end of my last stitch and started the next stitch with the new color, having a little knot at the top of the stitch. I mean I would cut the working yarn and tie the new color to it, and just keep crocheting away, so it was just one long piece of yarn in my experience. It is not exactly perfect, always a little unsure of exactly where the color will change at, and then there is the little knot, so it adds a slightly different texture.

Changing color at the last yarn over of the adjacent stitch

Smooth transition of color, see how the last loop of the purple stitch actually rests on top of the next stitch shown in the previous photo, creating a straight white line

Then I graduated to the point of changing the color after completing a stitch, and begin the new color with the next stitch. It was similar to the cut and tie method I did in the beginning, but I did not necessarily create a knot. I would cross the yarns over each other so that the last loop of the first color would get to loose. But if you look at this approach, it does not leave a smooth “straight” line of the color change, there is a little color overlap in the newly created stitch. The reason for this is due to the stitch construction for crochet stitches. The last yarn over and pull through of a stitch, actually creates the top of the next stitch adjacent.

So then I realized that I needed to change color at the last yarn over and pull through of the point of the color change. This gives me a cleaner color change, and a secure transition of yarns. It allows my work to have an appearance that looks a little more skilled. Granted I have ends to weave in, but this simple technique has taken my work to new level.

A Tail of Ends

ScannedImageWeave in all ends. Simple statement written at the end of almost every pattern, yet if you get a group of crocheters together you often find many different answers to how this is done. I have been on a personal mission to see if there is any consensus on this topic, and on my journey have found many opinions, thoughts and rationale for various approaches. Here are a few with their pros and cons, so that you can undertake a personal reflection and see what works best for your style of crochet.

First I need to have a long enough end. I admit yarn is precious so I don’t want to waste too much that I will just be weaving in, or cutting to throw away.  So yes, I have had short ends in some of my earlier work. I look at those pieces now and shake my head; the ends never stay hidden, regardless of which technique I try, the only thing that I can do to fix them is to pull out a needle and sewing thread and attempt to sew them down. I’m not a seamstress, sewing is not the reason I crochet, so I have learned my lesson, I leave an end of at least six inches in length, anything less is just asking for trouble.

Crocheting over the ends

Personally I have hated weaving in ends, so I have crocheted over ends whenever possible, this is quick and easy, but not exactly un-obvious. It does create a small ridge in the stitches that are crocheting over the end, and it is not very secure. If you give the fabric a good tug the end slides, and sometimes works itself out. Not to mention that the end is noticeable on the wrong side of the row, especially if it is a color change. Okay, so maybe this is not the best approach.

So maybe I should attempt weaving in, but I don’t want to get a tapestry needle. I take my hook and insert it through some stitches and pull the tail through. I don’t have to get up and find my needles and I am weaving in the ends not crocheting over them, but this is a little time consuming and the end looks obvious in some places as it sometimes is on the surface of the fabric entering into the side of a stitch. So unless I’m in a pinch on a personal item (that I don’t care about its appearance) I should probably stay away from this approach as well.

Weaving in ends over and through stitches

I guess I have to get the tapestry needle, now what. I can go straight across the rows, through the stitches but this gets me similar results to crocheting over them, if I give the fabric a tug it pulls out. So I ask around. I find people (even knitters) that have used some approach similar to those that I have attempted above, but then I find out some interesting tricks…work the weaving vertically through the stitches instead of horizontally, they are hidden better. But you can’t just stop there, you work the end in one direction for half the length on the end and then turn around and go back the other way, this will stop it from sliding out when the fabric is tugged. Genius! Why have I not found this before? Probably because crochet is as diverse as the people who love to do it. There is more than one right answer, so you have to find what works for you. I am sure that I have not found out all the tricks, more will be discovered, but at least for now I can hide an end and not have it slip out, since any good finishing should not be noticeable and should stay where it is put.
