I learned a good lesson about trusting my memory when I haven't done something for a long time, which is
don't!
I should have watched the youtube video first to refresh myself on how to warp the loom instead of thinking "I've got this." Twelve hours later I still didn't have the yarn all untangled after removing it from the loom so that I could do it right after finally watching the video.
The next day it only took me 90 minutes to get it ready and thought I'd be able to possibly get them done by the end of the day until I finally "got" what the instructions meant and had to order a different size yarn for the beginning and end of each towel. That should be arriving today so might be able to get going once I get home from work. Hopefully they turn out decent after all this.
