The last part was to stuff the liner in the bag, trim the top edge to match the zipper, and glue it in. Then punch through the leather, the zipper, and the liner and saddle stitch all three together. I have to give props to author Jessyratfink for this Instructable on saddle-stitching. When I decided to try working with leather, that was probably the most important tutorial I found.

The finished bag came out pretty well, my wife loves it! I can't wait to use some more of this beautiful material on future projects... and would have been really sad if it was just getting buried in a landfill somewhere.

Thanks for reading, and please leave a comment if you like! I especially value tips on construction techniques, as I'm still pretty new to this. If you're so inclined, please throw this a vote, its in the Before & After contest. Thanks!
