My mom and I did this when we traveled to Hawaii a couple of years ago. She had made quilts for my great niece and nephew (full sized) and we used the space bags so that we could get them in our luggage. She put one in her bag and I put one in mine. We also packed out clothing that way as well. I am happy to say the quilts returned to normal once we pulled them out of the bags and our clothing did too! Made it easy to pack!! lol
