I have a plywood box, no nails or screws or glue, unfinished, joined together at the corners with toothed edges, if you know what I mean. It was part of a stationery box set. Could I have holes/doors cut in the sides and upturn it for a hidey house? As far as I can see some of the hidey houses look like they are made of plywood and so my 'creation' would be very similar! Sound ok? Thanks
