I've never had to fix a bag where the leather has worn through to the piping. I've haven't been brave enough yet to buy a bag that needs that much work. The puffy paint sounds like its worth trying. I recall a post by a rehabber - ledobe or beccabaglady maybe - who first sewed over exposed piping then covered it with craft paint. My 'Leatherique crack filler' has arrived so I'm about to use that on the pin holes in the Twin Clutch. I'll post here after I've used it. That may be another option to cover piping?I know others have washed Sheridans. I have several and I've been afraid to wash them. But if I recall correctly, I did wash one and it came out fine. Now I have one with a hole in the piping. I'm thinking about trying puffy fabric paint to fix it. What do you think?
Good luck.
