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.
I can easily imagine my kids spending countless hours playing with this DIY outdoor kitchen. Except I'll probably add gardening tools to it. My kids r obsessed with gardening flowers and watering cans.
