A customer brought in three valuable stamps for framing. We will be floating them together on one mat with a second mat around the first. Originally we were sure we could purchase mylar folders that would fit around each stamp separately thereby not having to put any type of adhesive directly on the stamps. This would also give it a nice clean look. The problem is that we are having trouble finding these little pockets we dreamed up. Does anyone know if we could get them or where? Or do you have any other ideas? We ruled out corners because they would cover too much of the stamps. Thanks.
