I found this excellent tutorial and video via the leatherworker.com board I think is worth re-posting.
You can find the original blog entry and the cutting pattern here.
Here’s another pattern I’ve found. I like it a lot and the plus on it is, that no stitching is required. The stitching you see is only for decoration. If you don’t know how to make the feather on it don’t worry. Choose a different design or don’t tool at all. If you don’t have a pro-petal tool, don’t try the feather. You might be disappointed.
Are you having a template, tutorial, pattern you’d like to share? Please let me know.
