We so need to get a dining room set. Table, chairs, all that good stuff but in the mean time our dining room is a play area.
Part of that play gate was a craigslist find and 2 of the walls was purchased from ebay. It really came in handy in our last apartment though it was never actually used as a "play pen". I opened it up and used it as a large gate blocking the kitchen, hall, and bathroom.
Bought these stack-able bins yesterday at Wal-Mart. They aren't colorful and fun like other bins for children but they do the job at a fraction of the cost.
