Have you ever went to get sheets for a bed and had to dig just to find all the matching pieces.

So you will always have a complete sheet set, store all of the set in one of its pillow cases. When you need sheets just grab and go!
Something I always do is to store extra pillows in those plastic blanket storage bags. I found it helps keep dust and odors out, and its great if you have a child with asthma.
