With each set, she has created 3 totally different designs for a total of 18 quilt pattern choices. You begin by sewing the blocks in a row. Then, using the 1-2-3 square-agonals technique, you follow the clear directions. Make three (3) cuts, reassemble, sew and your row quilt becomes a dynamic on-point quilt design. There's cutting side or setting corner triangles and math calculations. Instructions are always clear and accurate with complete step-by-step how to in photos, illustrations, diagrams and text.
