I have used Ziploc Vacuum Space Bags for both storage and moving purposes. My old apartment was very tiny and I didn't have much closet space to store blankets and clothes that were out of season. These bags were a life saver because they would shrink down the overall size of the items and then I could place the space bags on top of my closet. Another time they were helpful was when I was relocating across country. I placed all of my sons clothes, stuffed animals and bedding items in the bags, as long with my clothes and bedding items. This saved so much room and was very easy to haul in and out. Once I was ready to unpack the items, I simply opened up the bags and everything puffed back up to it's normal state. Nothing was wrinkled or ruin during the process.
I would highly suggest any looking to save room to try these bags out. They are a bit pricey but I have been able to reuse them about 3 times so far and I believe I will get more uses out of them, as well.
