These mittens are made from reclaimed sweaters. I find coordinating sweaters to cut up, then resew. They are lined with super-soft minky fleece which makes them extra warm and cozy. My minky fleece can be scraps from my friends business, SwaddleKeeper, or since I know my winters are filled with making mittens, I look for remnents and sales throughout the year. The mittens are probably one of my favorite items to make since they each turn out differently.
