I have used them alot for many different projects, but smaller projects. They are great when you want variations in the same color. To me they are one of the best stash builders a quilter can have. I have a pattern for a quilt I want to make .. perfect for a ombre ... but every time I find one I like there is not enough yardage for that pattern. The pattern has a peiced medalion center with other piecing around the perimeter. Rather than have a large "open" area an ombre surrounding the center medalion ..light going to dark at the outside border would be perfect.
