I just mailed off 5 large afghan(Queen size) in med box. I used med size garbage bags and my husbands shop vac.We sucked the air out of the bag and tied it off. One of the bags got a hole and it started to come back to life. This would be a great idea for your storage of(yarn,fabric etc) stash. I was going to try this on my fabric stash. They sell these special bags for about 20$. I just saved money.. Barbara
