Actually, we are not "decorating" the inside of the containers. That may be one of the biggest misperceptions of this project. The containers act as framing and foundation. In the future, they will be cut mid-length in an effort to "join" or connect all the containers, but for now, they are merely storage space to fit that extra Christmas tree bought on sale.... or those extra ornaments, shoes, etc.... The containers act as foundation and framing for the rest of the house. -KGS
