Christmas Rug

Hooray! Tonight, almost two years after I started it, I've finished my little rug for the Christmas house. It's been one of those on-going things I pick up every now and then.

All I have to do now is work out how to get the fully laden shelves to stick to the walls. I thought I was being clever using a hot glue gun but because the walls are painted, they didn't stay up long. Surely I haven't got to empty out the house and sand the walls? Anyone got any good ideas, I've only got until Christmas!
