So many people asked about the warp spreader thingie, that I thought I'd add some more information. Janice said she bought one from Ken Colwell at The Looms in Mineral Point, WI, around 25 years ago. Now that I think about it, I believe that's where I got mine. Sadly, Ken Colwell and The Looms are long gone. For those of you who wish to replicate this handy device, I'm posting a scan and a photo to help you with dimensions. Notice that the two "legs" taper nicely at the bottom. As far as permissions, I have no idea who this belongs to. So you're on your own for that one. If anyone has additional information, please let me know and I'll post it.
To all those who sent anniversary greetings—thank you! I'm really touched and overwhelmed.
