This was a fun, gratifying and pretty quick project made from thrifted sweaters. This would make a great last-minute gift, as they went together in no time. They are slouchy, homely and hard to resist on a chilly day, and would be equally appreciated by both guys and girls.
Step 1: Gather your supplies
You will need a wool sweater (or two if you want your slippers multi-coloured), some wool yarn to attach the soles to the uppers, and a darning needle. I made a pattern for the foot with some newspaper.
I found a 100% wool sweater and washed & dried it several times to felt it. The fibres seized up and got worked together so tightly that it really changed the texture of the sweater completely. The other sweater was wool, but the percentage was unreadable (old sweater, old tag) and it did not felt at all. As you'll see, I used the thick and plushy felted sweater for the soles, and the other wool sweater for the uppers.
