DIY Sand and Rock Box by FSPDT. Gdjk -> made this with toilet rolls (aka tunnels) and moon sand instead of play sand. My son loved playing with it. The moon sand cleans up nicely indoors but play sand will be easier to play with when using the small cars.
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
