hello, i have discovered that changing the way i filled my original space saver storage bags made them stay flatter.
i needed batting for a quilt so i took a bag from one of the space saver "suitcases". while the "suitcase"
was open, i took all the batting OUT of its original manufacturer's plastic bag. then i put it back in the space saver and
sucked out the air. the whole contents went down much flatter than it had before and stayed down.
i think the original manufacturer's plastic bags didn't let all the air out and that is what kept that "suitcase"
bag from really getting flat.
