This is my picture of the most awesome DIY swift ever. I asked my tall engineer to make me one, and he put together a simple version. The next day, I came downstairs to find this double reinforced uber-swift. I figured out that it's exactly 53 inches around, so if I count the spins - I can do the math to figure exactly how many yards I've spun.

I've made little tags about where the yarn is from, how long it is, and when I finished it. It's working very well, and it's actually fun to use. My only complaint is that the set is so old that some of the pieces are worn and make it loose. The legs on the bottom tend to come away if it's moved, but it holds up nicely when it's being used.
