I recently discovered t shirt yarns.. I am planning on testing them out on a triloom. Most likely I will swatch with them first. They are tons do fun to knit with... I think they will give triloom weaving an edgy look. You can of course make your own... If you have a lot of old t shirts at home it is something to consider.. There are lots of videos on the web about how to do it.
