Here's a hat I made from an Old Navy sweater. I got the sweater at the thrift store where I get all my materials and it was in perfect shape. It's pretty new and I actually wondered if I should feel guilty for gutting it to make it into something new. But then I reasoned that it would be several new things, rather than one (re)used thing.
So then I forgot about it because this hat is adorbs. Forgive my bad sewing in this one, it was a quicky and those huge, wobbly fibers where running scared from my overlock machine.
