If you are planning to fly her to school, look into Bed Bath and Beyond to pick up her sheets and towels at the destination instead of mailing all of that. You shop in your home town, and they assemble everything you want to buy in the store near the college. Then, you can still buy only a portion of it, no obligation. Its a very nice service. Also all colleges offer summer storage, but she can store things with her sister, perhaps. There are also sheet and towel buying programs at some universities, a bit lower quality than BB and Beyond, and may not last all four years.
