Up-cycle Old Dishtowels to Make Rag Rugs

I keep a pile of dreadful miss-print towels for garage rags.  At a certain point, they are not even acceptable for mopping up spills because they have holes or paint on them.  Then I dye them with the leftovers from my printing colors.  I tear them into strips about two inches wide, and weave them into rag rugs.  I have a twining loom which is a simple wooden frame with a line of nails along the ends.  I wind a cotton string back and forth from the top of the frame to the bottom.  Then, I over-under-over-under along the width of the frame with the dishtowels.  It is simple, uncomplicated work.  I take the loom with me to market and weave during the down time between customers.  Some market days I can pretty much finish a whole rug.  I never plan a pattern, but I do try to keep to a color scheme.
Customers will see my project and stop by with their old towels at a later market.  Here's a photo of my current stash.
