Using the 1/3 yard of each light and dark fabrics cut the following (or the equivelent from your scrap bag):
Cut light and dark fabric strips 3-1/2" wide by whatever length (if this comes out of your scrap bag it is whatever length available, if cutting from a full piece of fabric it will be approximately 44")
Strip piece them together so you have a strip similar to figure 3
Press toward the dark fabric.
Cut across the seam for pieces that are 2-1/2" x 6-1/2"
You will need 36 of the pieces of the configuration similar to that shown in figure 4
When you have completed all of Part Two, you can go on to Part Three
