I've been seeing envelope clutches all over Pinterest lately and I've been brainstorming about how to make my own. I recently bought a good deal of leather from Tandy and got a bit of leather that looked like it would great for an envelope clutch. :D
This weekend I decided to draw up my own envelope clutch pattern and document how to make it - I've attached the pattern on step two for download.
If you've got everything on hand you should be able to make the clutch in about 15 minutes. :)
