Always used to have a door to stick the Dc's pictures to. Just used removable double sided sticky tape and it worked really well. We've moved and there would be a small panel of wall where the DC's toys are kept where we could stick some pictures but the wall is not a smooth finish. It would be stupid to stick sticky tape on that wouldn't it?
How should I go about putting their pictures up? DS is a very reluctant artist, but when he responds really well to seeing what he's done and then wants to do more so I'd like to have somewhere we can display things. That I can take down and replace reasonably regularly.
