S.B.
I bought milk crates at Walmart and stacked those around my son's closet we called it the garage. We did that for two years. WE kind of walled in the bottom of his closet with them. I just got rid of all the crates for some Expedit shelves at Ikea that are perfect for the large trucks. I bought some drawers to store smaller trucks and other items. Both ideas worked well and both were inexpensive.
