Rather, keep it in a large storage sack, hang it in your closet or lay it under your bed (but be careful for possibility of sharp edges on your bed frame). A long pillow case works wonderfully as a storage sack. I would not recommend a garbage bag because the lack of breathability may cause issues with any moisture in/on the quilt.
