Half the fun of a dollhouse is decorating and rearranging it (3/4's the fun?) and it sounds like Jenny and her daughter had a blast finding and making things for their cabinet dwelling. For example, see that groovy wallpaper in the kitchen? It's wrapping paper from Old Navy. Another nifty idea is the adhesive LED light that they put on each ceiling to illuminate the darker corners and make it fit for 24-hour play (because you never know when the urge to play is going to strike).
