While designing our workshop rooms we found a GREAT website resource. www.creativeforkids.com offers mural kits for decorating using any of a number of different themes (some based on specific Bible Stories, some just fun designs). We used the castle kit to design our "Kids of the Kingdom Castle" and combined elements of the "Candy Factory" and "Detective" kits for our Time Machine Room. The kits are very inexpensive and include transparencies and paint-by-number type instructions. The company has been very easy to deal with and the kits have allowed us to design beautiful and fun rooms for just the cost of paint!
