Potato Chip Block PDF Tutorial/Pattern

This is more of a tutorial than a pattern. By that I mean that there are lots of pictures demonstrating what to do rather than words describing what to do. The pattern is made entirely from scraps for the blocks. In my version I used up the extra pieces for the pieced outer border and used yardage for the inner border and binding. The tutorial describes how to make the blocks but does not tell you how many blocks to make. The quilt in the photo was made with 20 blocks.
