I like the store ideas and the ledge to sit outside. Also, like the bins for water play in the sandbox. The cover wouldn't withstand our windy environment. But would need a shade cover and a sandbox cover. Kona Sandbox with Canopy by KidKraft
You can use inexpensive fabric bins (Closet Maid brand ~ Target, WalMart) to temporarily stiffen your Large Utility Tote and keep it standing. The separate compartments could be helpful to organize a closet, for example.
