Any tips of getting the space saver bags flat?

Question

I used a few bags for my winter clothing and once i took the air out the bag was lumpy, so I'm not sure if it saves space or not. Any ideas of how to get the bags flat would be greatly appreciated

Answer 1

Use a vacuum to suck the air out. If it's still lumpy, get a cushion big enough to cover the bag. Sit on the cushion with the bag under and either vacuum out or sit until the bag is flat.
