This was a wooden castle that I found at Michaels craft store in the wood craft isle. It's a great size for The Harry Potter Mini Collection toy figures (Amazon.com). The toy action figures are all under 4" tall and perfectly playable for the Harry Potter fan. Also, what I liked about this project is that it was quick and easy. It took me about a week from beginning to end. It was fun and I used alot left over craft supplies I already had.
To decorate my interpretation of Hogwarts I used scrapbook paper, stickers, bits and bobbs, miniatures from the fairy garden isle and half scale miniatures. Some stuff I had, I wasn't too picky about the paper, stickers or even the accessories. Some of the tiny furniture had to be modified or painted. I even used some Lego pieces. I just wanted to have fun with this project. I also used two strands of moon lights (one each side) to illuminate Hogwarts.
