Hey all, I’m a novice who’s getting back into crafting now that for the first time ever I have a dedicated workshop. I’m working on a breast plate that I cut from leather I’ve actually had for a couple years. It’s dyed with water stain and finished with Fiebing’s leather sheen and today I noticed that the part that bends around my sides has tiny, discolored cracks or wrinkles. I’m wondering, is the leather too old, did I put on too much sheen, can this be fixed?
