The Dee by Dee is a quadrant with 121/2 inch radius. There is a printed arc from 4 to 12 inches, with markings at half inch intervals. From the centre point there are 13 solid lines radiating out to divide the area into 12 segments.
At the intersection of each segment and inch arc line there is a hole to be marked through. Between these segments are a further set of holes to divide the area into a maximum of 24 segments. This allows division of 96 when placed in a circle. Designs can be done in quarters or less, semi circle or a full circular design.
