I want to do this to the playroom doors! ikea sells this system. great way to portion off or "hide" a small room/nook. easy way to turn an alcove into a guest room if you don't have a full spare bedroom.
IKEA picture frame hanging hack from A View Along the Way. Amazing FREE trick for hanging picture frames in a grid, with no more frustration. Would work on any other frame with a wire across the back too.
