A really good way to store quilts is to lay them flat on an unused bed. Think I learned this at a quilt show in Roswell, Ga. The quilts were stacked on top of each other. If you are concerned about dust, place a cotton sheet over the quilt stack.

Currently, mine are stacked on the extra bed or displayed on a quilt rack.

However, if I could afford one of these...

Think they're beautiful!
And no, I don't work for these people or even know them.

I have a wooden quilt rack in my living room that I found at a thrift shop for $5.

I have a big pile stored in cotton pillow cases on the top shelf of my closet. Get them out and refold every now and then.

I use two quilts on each bed, the older one underneath. I have a few in the drawers of the dresser in the spare room.

DonnaPBradshaw: Great idea, especially the coordinating fabric bag. If you don't have enough to make an entire bag, sew a row of fabric onto the plain sleeve at the "view end" or simply make a tag with a piece of fabric that indicates the quilt colors inside the bag.

I visited a quilter who stacked her quilts on an extra bed in her home. There were layers upon layers. This way, they were not folded.

Display them. I have a friend who has a couple of old wooden ladders that she uses to display her quilts. She can display quite a few that way.

are they still in good enough shape to donate? someone always needs a quilt.

I had a friend who bought a new metal ladder, took off all the stickers they come with, spray painted it to match the room, and used it for her quilts. Looked great.
