We have our son temporarily moving back in with us while he is waiting for a home to buy. My wife had been very frustrated with our lack of storage space in our 3 bedroom home. As a desperate move to assist my wife, I stopped by Walmart and picked up some of those vacuum storage bags. You know: fill them full of clothes and/or bedding, apply the suction hose from your vacuum cleaner and it shrinks down, rather dramatically right in from of you. Since my wife has been thrilled with the early experiment, she asked to buy some more of those bags, today. I did and she is impressed with the available space she now has for those same items. I do not get a commission for sharing this; this is one of those gizmos that really does what it says it will do. Try it, you'll like it.
Been using them for years. All seasonal clothing goes into them until they are needed again. They come in a large selection of sizes as well.
