Painting with Wool
I started with a (rummage sale) fuchsia wool sweater. Great color but otherwise not so cool. I put it in the washer & dryer to “felt” it and cut a piece out of the back. Then I took some colorful fluffy wool roving, laid it out on the sweater and used a felting needle (a large needle with little barbs) to poke the roving into the sweater backing. Quite addictive & comforting, its like painting with wool. You can find all the supplies you need to start your own experimenting on Etsy, as well as items for sale that are alternately beautiful and downright scary.
