I’ve been wanting to publish a pattern for a simple crochet rainbow wall hanging since I first wrote about macrachet last winter. Back then, I almost absent-mindedly crocheted a simple rainbow, more to illustrate the concept than to create something particular. The rainbow came together so quickly and effortlessly I didn’t bother taking any process notes. After all, it’s a rainbow. An arc. A half-circle. Who needs to take notes on that? Plus, I thought to myself, if it turns out well, I will surely write and publish the pattern within a few days. There’s no way I’ll forget between now and then.
