Dorm needs, and fun items for dorm room decorating, should be considered before leaving for college. Make a dorm room checklist early so you can add items as you think of them. But, it is important to know the dorm room rules, and keep your items consistent with what is allowed.
Some items should be available from the first day. Other items will require that you find out the details of what is allowed before making a purchase. Some items can be brought with you, others may have to be purchased in the city in which the college is located, and still others may be best bought online and delivered to your dorm. It may be a practical matter since large, heavy items may not fit on an airplane, or even in your vehicle if you are driving to college. And, the large, heavy items might be too much to handle alone.
