The BIG thing to remember when packing fabric in vacuum bags is - FABRIC IS HEAVY. I love using vacuum bags with my fabric, started off putting them into a large tote. One full vacuum bag on top of another, thinking DH wouldn't know how much fabric I had. WRONG!!!!! When I went to care my tote to another room for storage, I pulled my back out. If you place 10 pounds of fabric into the bag and suck out all of the air, you still have 10 pounds of fabric just in a smaller space. So for me I had over 100 pounds (not SMART on my part), as you can see I wasn't thinking. So DH found out how much fabric I had (but just in the one tote), now I move my fabric one bag at a time (so he doesn't know that I have more - lol).
