Wood pallet sandbox, with bench seats that unfold to cover the sandbox! I hate sandboxes bc it's like an outdoor litter box for wild critters. Love that the cover will keep them out! Hubby is going to hate that I found another pallet project :D
An Ikea Hack custom train and activity table with TONS of storage. This is such an an EASY DIY project and a great way to get all of those toys up off the floor and organized once and for all! Maybe a Lego table and storage?
