This was one of the fastest knits I've ever done. The most time consuming part was making the bind off edge look the same as the cast on edge, as I wasn't thinking of it before knitting. I use the backwards loop cast on most often, as I rather like how it looks. Sometimes an actual edging is nice, but I like how the backwards loop just kind of lets the knitting appear instead of giving it a starting border. As this piece is so small, I realized that having a matching cast on and bind off would make it look a lot better. Off the top of my head, I can't think of anything that would match it. I know EZ's sewn bind off matches a long tail cast on, and I did a quick search to find something that would work with a backwards loop, but it seems like it's the least used among those who want to match their cast on and bind off and doesn't really have one.
So, I cut a long tail and went about trying to match my cast on and bind off edges. Calorimetry has 120 stitches you are casting off, and in a worsted weight yarn on size 8s, I did not want to cut a tail three times longer than what I was trying to bind off. It would have taken forever and tangled quite a few times. I'm using Cascade 220, which is a wooly wool, so I can certainly spit splice the ends anyway to get the edge I want. I've gotten something near correct - it's not perfect, but I gave up trying to get it 100% right. Nobody will be looking at the edges that closely, and it's better than a normal bind off.
