My son is at college and I saw the list of "Don'ts" that the dorm housing authority handed out. Don't paint, don't hammer nails in the walls, don't put glue on the walls, don't hang posters with gummy tape, etc. etc. So his room is looking rather bland - until these came out. These are fantastic for rented apartments or dorm rooms where the lists of "Don'ts" crimps your decorative options. They work great, don't leave adheasive on the walls, they hold pictures or mini posters and my son got creative and used the "outside" of the frames put end-to-end to make one huge poster size frame for a poster, which of course is surrounded by many smaller frames with pictures in those too. These have made my Christmas shopping a lot easier for this year - and there are some really colorful Choo-Choo Trains with the windows cut out where you put the pictures, so the kids have a train to play with that can be moved around the wall and their pictures are always displayed so cute! Fantastic idea.
