I use a lot of yarn and other fibers. It would be really interesting to see the acrylic yarn I use turned into new yarn or stuffing for other projects I work on. It wouldn’t take much to make this work because yarn can be broken down and turned into new fiber pretty easily. It would require fiber artists to send their scraps back to yarn companies which would require all the colors to be mixed up. Though they would need to be separated by type because specialty yarns probably couldn’t be recycled in the same manor. With normal acrylic fiber it would just take the separation of those fibers, possibly the bleaching and dying, the washing, and then re–spinning to turn them into new yarn.
