Blueprints

I have zero building skills, although I do okay at decorating... or at least arranging furniture. (My wallpaper/floor pattern skills are also pretty much nonexistent.) I'd probably benefit from at least looking at blueprints and using them to put together something more interesting than the Lego houses I usually create. But the way I play, I tend to build when my sims don't have much money. So I just put up the walls and flooring and shove the cheap furniture wherever it fits until the family can afford a full set of upgrades.
