DIY: Bubble recipe and refill station. Love the idea of reusing plastic cups from restaurants as the containers. Keep the bubble solution confined to one big refill container, and no worries about leaky, yucky containers hiding all over the house!
The Thomas the Train snack train made for third birthday party. It's just two packs of aluminum loaf pans from Walmart (mine came with plastic lids-great for leftovers), a roll of black electrical tape and of course, Thomas.
