Which width of cloth pads??
You might check Etsy if you haven’t already. I know a lot of the pad makers don’t put snaps on the pads until it’s sold, so you might be able to request for the snaps to be placed so that the pad has a narrower gusset.
Most of the pad makers are really nice, just send one or two a message and see if they can do that for you.
Good Luck and Happy Shopping!
