Crochet Quilt Blocks- the Half Square Triangle

Crochet quilt blocks lend themselves to unlimited creativity. These can be great for scrap projects or planned out artistic works.

Below I describe how to create your own simple geographic block, as well as some idea suggestions.

Ohio Star Crochet Quilt Block

In the world of quilting the half square triangle, even using just this block, the possibilities are endless. Essentially it is simply a square that is worked with two colors. It is divided on the diagonal, creating a look of two triangles with the long ends together.

Sizes for crochet quilt blocks

Create your own design, just ensure that these blocks are the same size, or equal fractions of each other. Meaning make big and little blocks. The big block might be 10” then the little squares should be 5” so that they can all be put together equally.

Getting started with your crochet quilt blocks

To begin, create a chain the desired length of the diagonal of the square. This chain should be an odd number. Work a single crochet decrease over the 2nd and 3rd chain (need to know how to work a single decrease, check it out here), single crochet in each chain across until 2 chains are left.   Single crochet decrease over the last 2 chains, then chain 1 and turn.

All subsequent rows of this half of the square are worked the same. Work a single crochet decrease over the first two stitches, single crochet in each stitch across until 2 stitches remain, then work a single crochet decrease over the last two stitches. Repeat this until only 2 stitches remain, and then single crochet decrease these tow stitches together.

The next side

Using another color and the unused loops of the beginning chain. Work the same stitch technique of decreases on each side of the row.

The block is really just that simple. Now for some ideas. I have found plugging the term “half square triangle quilt” into a search engine, and then selecting the images option, that there is a great abundance of uses.

Ideas for Crochet Quit Block -Half Square Triangles

Some of my favorites are the Ohio Star block, Flock of Geese block, and Pinwheel blocks. The half square triangles that are created can be put together to form these larger blocks, then these blocks can be put together to create pillows, blankets, ponchos, the possibilities are only limited by imagination.

Music Tapestry Block for Crochet Celebration

Do you hear the Music? Happy National Crochet Month! I am part of the annual Crochetville Blog tour to celebrate the event. This year the theme is Crochet Concert and features how music can be an inspiration, as my inspiration I have created a Music Tapestry Block to Celebrate crochet.

I Celebrate Crochet with Music

As my contribution to this tour I have created a Music Block. Use this block for various things including as a contribution to Warm Up America.

Music Block

You can donate to Warm Up America as a nationwide organization. Donating locally is encouraged, however donations can be sent to their office to be assembled. Assembled blankets will be donated through the United States.

Tapestry Crochet to Create Music

The Music Block gives you an opportunity to learn Tapestry Crochet. Tapestry Crochet is a technique of color work that has you crocheting over the unused color. This reduces finish work and creates a solid, somewhat dense, fabric.

Tapestry Crochet is worked entirely in single crochet with color changes.

Worked entirely in Singe Crochet (Double Crochet if you are using UK terms). Worked with a chart, where each block is 1 stitch. Just remember to work back and forth in the chart, meaning read right to left for odd number rows and left to right for even number rows. (Needs tips for changing color…check here).

Crochet over the unused color, and carry it across. This reduces finish work while creating a charted design.

Enjoy this technique, and take some time to celebrate crochet this month.

Rolling Along Block

Working the Catherine’s Wheel

Catherine’s Wheel is a classic crochet stitch that works one row of shells over a row of decreases to create a circle or wheel look. I have made a couple of changes to the classic pattern. For starters instead of working a single crochet after completing the shell or decrease, I work a slip stitch. I find that this help prevent “gapping” that occurs in the chain 3 area.

Working a dc9tog, you will have 10 loops on the hook.
Yarn over and pull through all the loops on the hook.
Slip stitch worked after the chain 3, to secure the decrease.
Working a decrease on the corner, dc5tog.

I should also point out that I work the shells in “the center of the decrease”, this is the biggest opening. However it is really not the completion of the decrease stitch, but the third chain. I feel that working here emphasizes the “center”, when working in the actual point of completion just looks a bit wonky.

Work the Shell in the center of the decrease, it creates a “hole”.
Working a shell at the beginning of a row means working in the center of the decrease.

I do have an exception to this, and that is when finishing a row with a shell it needs to be worked in the top of the turning chain to keep the edge straight. This will be just over from the “center”.

The “exception” the last shell is worked in the top of the turning chain, this helps to keep a straight edge.

Gauge

7”x9” rectangle

Materials

Medium weight yarn, in 2 colors MC (main color), CC1

K/10 ½/6.5mm crochet hook

Special Stitches

Double crochet 4 together (dc4tog): Working over the next 4 sts, [yo, insert hook into next st, yo, pull up a loop, yo, pull through 2 loops] six times, yo, pull through all 5 loops on hook.

Double crochet 5 together (dc5tog): Working over the next 5 sts, [yo, insert hook into next st, yo, pull up a loop, yo, pull through 2 loops] six times, yo, pull through all 6 loops on hook.

Double crochet 9 together (dc9tog): Working over the next 9 sts, [yo, insert hook into next st, yo, pull up a loop, yo, pull through 2 loops] six times, yo, pull through all 10 loops on hook.

Note:

Change colors without fastening off the yarn. Instead carry the yarn along the edge, and it will be hidden in the edging round. Here are some tips for do it.

Tunisian Crochet

This block is used working Tunisian Crochet. Tunisian Crochet is essentially inserting your hook through your fabric and pulling up a loop, and leaving the loop on the hook, pulling up loops across the row. Then a “return pass” is worked to work each loop off the hook. This creates a fabric that has a similar look to weaving, yet has the same structural characteristics as crochet. There are many different stitches in this technique, but in this block I only use one stitch, the Tunisian Simple stitch. Learn the stitch here.

Changing color on every forward and return pass, creates a dramatic effect. Utilizing only three colors means that I have a color waiting for me when I finish a row and I know exactly which yarn to work next.

Gauge: 7”x9” rectangle

Materials

Medium weight yarn, in 3 colors MC (main color), CC1, CC2

9 mm Tunisian Crochet hook

Special Stitches

Tunisian Simple Stitch (tss): Insert hook from right to left under next vertical bar, YO, pull up a loop.

Return Pass (RP) :  YO and pull through 1 loop, [YO and pull through 2 loops] across, until 2 loops remain on hook, using new color for next row’s FP,  YO and pull through last 2 loops.

The Pattern

With MC Chain 19

Row 1: With color MC, pull up a loop in second ch from the hook and in each ch across. Switch to color CC1, RP. 19 sts

Row 2: With color CC2, tss across, switch to color MC, RP.

Row 3: With color CC1, tss across, switch to color CC2, RP.

Row 4: With color MC, tss across, switch to color CC1, RP.

Row 5-19: Rep Rows 2-4 five times.

Edging Rnd: With color CC2, sc in each vertical bar across, 3 sc in corner, work evenly sc around block working 3 sc in each corner. Finish off.

Leaf Spike Block

Even if you do not want to participate with Warm Up America, please consider creating blocks, or blankets for your local community. There are various places in every community that accept donations.

Spike Stitches

This block is used working spike stitches. Spike Stitches are essentially inserting your hook through your fabric and pulling up a loop. This loop is pulled up to the height of the current row to have the stitch finished. This gives a unique ability to create fascinating lines of color. In this block I have worked 5 spiked stitches together to create an affect similar to a leaf.

Gauge: 7”x9” rectangle

Materials

Medium weight yarn, in 2 colors MC (main color), CC1, CC2

K/10 ½/ 6.5mm hook

Special Stitches

Spike Leaf (SL): Insert hook in the 2nd stitch backward from the hook and 1 row below, yo, pull up a loop, yo, insert hook in the 1st stitch backward from the hook and 2 rows below, yo, pull up a loop, yo, insert hook in stitch directly below and 3 rows below, yo, pull up a loop, yo, insert hook in stitch 1 stitch forward from hook and 2 rows below, yo, pull up a loop, yo, insert hook in stitch 2 stitches forward from hook and 1 row below, yo, pull up a loop, yo, pull through all 10 loops on hook.

First insertion, yo, pull through loop of Leaf Spike
Second insertion point of Leaf Spike
Third insertion point of Leaf Spike
Fourth insertion point of Leaf Spike
Fifth insertion point of Leaf Spike
Yarn over and pull through all 10 loops on hook. Stitch complete

Notes

Working the first stitch immediately following the Leaf Spike can be a bit tricky, as you need to push the last loops of the LS out of the way.

After pulling up the loop through the stitch immediately following the Leaf Spike, you will need to push the last loop of the Leaf Spike toward the stitch to maneuver the hook into the next stitch.

The Pattern

Row 1: With MC, ch 24, sc in 2nd ch from hook, sc in each ch across, turn. -23 sc

Rows 2-5: Ch 1, sc in each st across, turn.

Row 6: Change to CC, ch 1, sc in same st, sc in next 2 sts, LS over next st, sc in next 5 sts, LS over next st, sc in next 5 sts, LS over next st, sc in last 7 sts, change to MC, turn.

Rows 7-11: Ch 1, sc in each st across, turn.
