I just finished a bag I cut out of suede about a year ago. Decided the suede was too soft, so I just let the pieces lay. After lining a bag cut from Tandy's Deertand leather (very soft) with pillow ticking, I really liked the results. Sooooo, long story short I dug out the suede pieces and tried it. Danged if I don't like the results a lot! I'm gluing the ticking right to the inside of the leather using rubber cement, so it adds just the right amount of thickness and stiffness. I can guarantee I'm not going to be passing up any more suede at the thrift store!
BTW-
I've always liked the looks of thicker, harder leather in bags, but have since discovered they have a real downside. When you sneak through brush for your deer, those leather bags really make a lot of scratching noise. Soft bags are silent. From now on all my hunting will be done with soft bags, and the cool looking bags are going to be range queens.
