A stitched band of 3 jelly roll strips each 2 1/2" wide will make a 6 1/2" band of
strips. To make a design you need 3 similar light coloured strips, 3 medium
strips and 3 dark strips. Alternatively, use 3 strips each of 3 completely different
colours that work well together. Large 60° triangles measuring approximately 20 3/4" along outer edge.
