Hi ladies! I'm thinking of adding a long strap to a Fendi Mama bag (dark denim) so that it can be a crossbody. What do y'all think? I'm kind of crafty so I think I can make a strap myself pretty easily. I love the mama shape, but I'd like the crossbody option. With the large flap I think it would almost look like a smallish messenger bag. Am I crazy here?
