Toilet Paper Shelf - Just buy a "shadow box" from a craft store and paint! (I probably wouldn't use this idea specifically for a toilet paper shelf, but worth remembering for other places around the house)
Stuffed Pizza Muffins- these are awesome! I use shredded mozzarella rather than chunks of string cheese. How in the hell would you neatly roll THOSE up? Also, we call them pizza rolls b/c pizza cupcakes sounds stupid and revolting.
