Tonight I cut out the front of the sporran from the springbuck pelt, 9" in length, and the gusset 3" wide. The width is 6.25 inches. I bought some heavy leather, enough to do the entire back of the sporran if necessary [think really stiff] and several yards of garment leather. Going to try both and see which works best. I'm taking photos as I work and will post when I finish.
