This is the loom 'waste' left over after weaving 10 towels. It is less than 2 ounces. Add the 'waste' at the beginning where I tied on, and the loom waste comes to about 2 ounces, or about $2.
I don't fuss too much about the amount of 'waste' involved in weaving. As I've said before, the biggest investment in making hand woven textiles is time. By the time I design the warp, wind it, get it into the loom, then weave it off, cut/serge the towels apart, wet finish them, hem them and give them a final press before tagging/pricing, that $2 is a drop in the bucket of what has been invested in making these towels.
So I focus instead on how to work more efficiently rather than spend my time saving these thrums and then trying to make something useful out of them. I could have woven another 3 or maybe 4 inches on this warp, but why?
Instead I send the 'waste' off to be recycled, just like I do my paper, glass, cans and plastic 'waste'.
We all get to decide how to invest our time. I prefer not to use it trying to save $2 worth of yarn. YMMV.
