I am on a campaign to promote 3 1/2" strips. They show off so much more of the prints than 2 1/2", and the projects go so much more quickly.
This simple jewel of a quilt is made with 30 3 1/2" strips. It can also be cut from 20 Fat Sixths (12"x 22") or 15 Fat Quarters. With the Fat Quarters, you would probably have enough left over to do a pieced binding or add a pieced border.
For my model, I liked pairing up 2 similar colors, so it looks like a shaded square. I also made it in our Asian strips. I have seen it in totally scrappy, too, and it just sparkled.
The patchwork finishes 54"x 60" for a throw. And you can also just keep going with more patchwork or borders.
