Potato chip quilt (try to stop at one ...)

Other quilt designs are also sometimes called 'Potato Chip' (for the same reason), but this one seems to be the most common around the internet. Break out a jelly roll, or those 'spare' strips that have accumulated, choose a contrast fabric, and you'll have this quilt top ready in an afternoon.

Kay Sorenson of Quilts + Color shows a number of examples, and provides a tutorial here, under the title Sunrise-Sunset Quilt Tutorial.
