Some folks use the store bought quilts to make quilted jackets, purses etc. I've seen a few that people have made and they are really nice. I think once you've quilted you can see the difference in the quality of workmanship and fabrics but if you don't quilt you wonder why anyone would pay hundreds of dollars to make a quilt that can be bought for $25 - 50 in a store. I know my neighbor does.
Just my 2 cents.
