Cheryl,
Yes, the rack goes in the hamper to hold the dies upright and separate them so the blades don't touch. I don't want to see the dies out but still want them easily accessed. My room is small so organization is key for my sanity. LOL.
The hampers also function as a space to put my sewing box with supplies and scissors. I also use another one of the AQ racks to hold the light box, scanning mat, and one GO Big die.
The hampers are very sturdy. Hope that helps!
