Shrink wrap is the perfect final addition to a gift basket. Besides giving a polished finish, shrink wrap holds items in place preventing slippage of carefully arranged gifts. Although shrink-wrap comes in a variety of forms, the individual bags in small, medium and large are the cheapest and simplest to use. Available at your local craft store, shrink-wrap bags are the beginner's dream. Be sure to pick up a few bags as shrink-wrapping quickly becomes addictive.
