My yarn is very soft, and the pot squished out of shape whenever I touched it. I thought of stiffening it, but didn’t want to lose the softness of the yarn and didn’t know if stiffener would work on that type of yarn anyway. So I followed the instructions at Clothesline Crochet and crocheted both the pot and the lid over some synthetic clothesline I bought at Walmart. The site says 100% cotton clothesline is best, but I can’t imagine where you’d find that. It was easy to do and it worked out really well. It’s still soft to the touch, but the shape is firm.
I used a J hook and followed Marlo’s pattern for the most part. I free-formed the handle (using an I hook) because I wanted it to look pointy, like the original one she made.
