You could attach them to strips of a solid (black or white, your preference) and have the color blocks staggered. In other words, start one strip with an 8" strip, then a color block, then a 10", and a color, and a 10", and on until you've used four colors and have a strip 48" long. Then do another strip, but attach it with a 10" starter next to the 8" starter to staircase the color blocks a little. You'll end up with 24 strips, for a width of 48". If you found a good border print, you could have a decent lap quilt, but you'll use up a lot of the background fabric!
