I made it!
I made this bag! I'm so proud of myself! Even if it's a little wonky! I ran a wool Old Navy sweater through the washer on hot a couple of times to felt it, then cut and pinned and repinned and recut and sewed and ended up with this little guy. It's based on this idea: 30 minutes to a recycled sweater bag but it took me considerably more than 30 minutes.
