What are you most proud of? That I was able to fit the pattern pieces from the re-purposed leather pieces. I designed it to have front and back pockets due to the limited material and piped the front pocket to distinguish it easily from the back. I'm also proud that my seams match and that I was able to sew my seams without too much stretch since I didn't have the cold rubber tape. What advice would you give someone starting this project? I did not make the wool felt sample :( but I did review the entire course once quickly before I attempted to make the bag and follow Don step by step. If you are using brand new skins ($$) you might want to do the wool felt sample first. I took the chance because I had sewn a leather purse before.
