Here are a couple of pictures of my first ever completed project. It’s a two-color spiral rug crocheted from jute gardening twine, two strands per color. Half double crochet throughout. It is 3 feet across and the biggest challenge with this for me was figuring out the correct number of increases per round. Too many increases caused warping and ruffling. Too few caused cupping. After ripping back the same 10 rounds 5 or 6 times, I began to feel strongly that there had to be a mathematical answer to the problem. I’m not particularly mathematically inclined but I did recall from high school geometry something about the diameter and the circumference and pi. I looked it up in Wikipedia and bingo. The diameter times pi equals the circumference. I figured if I knew the length of the upcoming round (circumference of the rug after the next round), all I need do is take that figure and multiply it by the gauge and I should know exactly how many stitches are required for the next round. And without going into a lot of detail that’s more or less how it actually worked. No more ruffling, no more warping, no more cupping. Thank you, Euclid!
