Very disappointed in this product. It wonít stay glued and keeps collapsing, knocking stuff off the shelf and making a big mess. I glued it twice with different glues and it still wouldnít stay glued ÖSO I punched a hole in it with my long reach Cropodile and secured it with a brad as a temporary fix. The cropodile only reached one corner, unfortunately, but I will drill another hole and secure that with a brad also. I think that will work. Most products from Scrapbook.com are great, but this one isnít. I think the problem is due to the very slick, shiny surface.
