For your project, I would not use batting, I would use a well washed blanket so no quilting would be needed. If you are using real suede, how will you keep it clean? If you are using faux suede, you can do the same and never put it in a dryer, and only wash it in a “big boy” washer at a laundromat, and hang it on a shower curtain rod (moveable type that is wedged up, not nailed, inside the shower stall) with the quilt folded in half for a few hours, then turn it over so each side gets time to dry without creases. Good luck with your project.
