Pictures of shelves. The shelves themselves are about 12mm MDF with a 25mm high x 10mm thick lipping on the front providing an upstand to stop things sliding off. The support pegs should be commonly available (if not, I've got lots of them) but you will have to be VERY careful not to drill the holes too deep and come out the other side. Mark your drill-bit with masking tape. We put shoes on the bottom - hence the newspaper. Note the small block fixed to the underside of the shelf right behind the peg - to stop the shelf moving forward.
Sorry no photos, I can't work out how add them to this post. Please either tell me how to do it, or give me an email address.
