The other day, I had 3 T-shirts.
Yellow, Rust, and Very-Orange.
Then, I cut them up ... each t-shirt into a single strand of inch-wide fabric. (Easier than it sounds, really.)
Then comes the fun of - - - stretching - - - the "yarn" so it curls ...
And, since I don't have any projects going right now that need this much orange or yellow, I'll be listing these on eBay or Etsy soon, in case somebody else does!
