My son will be attending VMI in the fall and I have begun to stockpile the things he'll need. After several unsuccessful attempts to locate twin XL white flat sheets, I found www.linensupplier.com. They have the sheets (as well as many other things on the list) and the prices were very reasonable. The sheets are sold by the dozen, but if you call them, they'll let you buy a smaller quantity. They also donate a portion of your purchase to the VMI Parent's Council. Just thought I'd pass this along in case someone else is having the same trouble I did!
