This was a project I did that included many of my favorite crafts!
The first step is to crochet a bag using 100% yarn. Wool yarn is the most important part of the process because you are only able to felt natural fibers and wool works the best.
I crocheted a simple bag using a DS. It had an oval bottom and turned up sides. I made the pattern up as I went along. If you need an actual pattern you can find many options on Raverly or Pintrest. Additionally I added 2 straps from the side that tie on the shoulder. This way I was sure that the length was right for my body.
