Whoever associated plaid with "ludicrous speed" wasn't a weaver.
@amerika Thank you! It's slow going but I'm really enjoying it all the same.
The slow going is part of the fun. It's mesmerizing, or at least seems to be when the people around me knit and cross-stitch (which looks difficult as heck, with lots of math).
I put a piece of masking tape on my loom and wrote down the Forbes Tartan thread count so I could keep track. This project will require three complete passes.
