Polystyrene has now been disposed of, and I stopped in for some more packing materials on the way back. Oh, alright, it was actually the craft resource rescue place, and the packing materials are mostly bits of fabric etc., but close enough! I also grabbed a couple of rectangular tins with hinged lids which were some sort of promotional hair care thing, but will be great little rubbish bins for the bathrooms. I had plans for a big coffee tin, but these will work better - I might even cover them with the wallpaper I found.
