The Square Dance Block uses a single template available in three sizes, 8″, 6″ and 4″. The “size” marked on the face of the template is the finished block size. The template has engraved on its face the widths for the strips for pinwheel arms and center.
How you intend to use the block determines how it is assembled.
If you are using the block to produce a pinwheel pattern, make sure you use a design wall to lay out your pinwheels. Until you are comfortable with assembly pull one block off the wall, assemble it and return it to the wall before starting the next block.
If you are using the block to distribute color for a watercolor image, use a design wall to lay out the colors. Work with a couple blocks at a time.
