I'm lucky I have 12 shafts with 14 treadles....that allows me to do a lot and the Spring loom isn't so large that the treadling span is a big reach. Turned twill is so easy to jazz up because you really are working with 2 sets of treadles (I can work with 3 because of the extras)....so you just get to have fun playing with 2 things...watching squares appear and then you say...hmmm, maybe a little rectangle would be nice...."oh, that's gorgeous" , I'll turn it into a repetitive sequence...holy, crow, look at that. Oh heck, how long is this.....okay, stop and measure....shit! shoot!, it s 3 yard towel. ha ha.
