They would join at through chain loops, and I found that I was working along splendidly, then put things down and come back and have the joins twisting. I could not for the life of me figure out what was causing this difference. I was entering the chain in the same direction, I was making the same number of stitches, and so what was my hold up? Was I distracted? Were my fingers and hook no longer obeying?
Then, I noticed a very subtle difference….where was the working yarn drawing from? In every instant that I had a problem with the join twisting the working yarn was in front of my work, in front of my hook. This was the cause of the difference. Usually my working yarn is always behind my hook, this makes for a smooth fabric and joins that behave, but the simple acts of letting the working yarn get in front of the hook and everything goes backward.
This is similar to the effects of how you “yarn over”, the placement has very subtle and telling results (for a description of that post check out “How do you YO?”). The working yarn in front of the hook creates an extra twist to my join and, though creates a more textured fabric, is not necessarily the effect I am looking for.
So I put a little extra knowledge of how crochet stitches work in my basket, and will have to play with it in the future and see what effects it can create, that I actually intend for.
