I've made a Holiday Gingerbread House for you to enjoy! It has one channel the gingerbread is recolorable, the bits and pieces, are not recolorable. Found under Decorative/Misc Decor.
I've taken the texture from the sims 2 brick floor, slate and bricks and turned it into a sims 3 pattern for you to enjoy. 2 recolorable parts. Found under rock and stone. Packaged as a .package file.
