I would knit a giant swatch and then practice crochet! When I was considering changing my knitting style to loosen up my gauge, I started making this mammoth swatch out of crunchy acrylic yarn. I am kind of between projects. Well, more that I started a project with which I am not thrilled. So, instead of working on that, I just picked up a crochet hook to add a border and even out the swatch. My elder elf has appropriated it for her dolly.
This pic shows the true size.
I have learned that I mostly know how to crochet- I have been taught several times. I still don't know how to turn around without losing stitches so that the finished project is a square. I don't know how to go around corners well. Crochet is really pretty quick!
