With the purchase of a walking foot machine. I made my first leather project for see what the machine can do and don't. I really love this machine but I will choose to go with real leather on the next projects instead of vinyl because "the toughness" of the real skin. There is a lot of work to do a bag like this and it's the same work to use vinyl or leather and the real skin will pass the test of time more than any other material... It's a hint.
