We started by cleaning out our garage on Saturday. Love that the in laws have a fancy power washer for the nasty garage floor. We then bought some shelving and got all our stuff off the floor and up onto shelves.
Inspired by Brooke, I got together some baskets I already had, purchased some inexpensive boxes from IKEA and used my label maker to clearly mark what is in each one (crafting, cords and manuals, gift wrapping, etc). She wraps her shelves in fabric, so I am going to do that too, but I haven't had a chance to get that far. Holy cow, I can't believe how much bigger my house seems just with these two changes. Next up.. Food Storage!
(seriously.. there aren't before pictures because it was absolutely mortifying!)
