Also, remember you can cut the strips just like you would any other fabric-- you don't just have to use them as strips. I've used the EZ jelly roll ruler and also the EZ flying geese ruler to make half square triangles and Flying geese using jelly roll strips and then used those with other fabrics in various quilts. The most recent one I did that way was a Jacob's ladder quilt.
You can also make strip sets with them and then cut those into squares, half square triangles, etc.
