This is a very clever technique to get a difficult looking effect from a really easy process. It's as simple as sewing squares together and add the borders, lining up the template to cut out new squares, then sewing them back together creating a totally different look. It's fast, fun, and addictive! The Primitive Pinwheels Template makes a 1" finished block. To top it off the template has an included free pattern to get you started.
