Circle Rulers by Riley Blake for Lori Holt - size 2" to 12" (Please read shipping note)

NOTE: Ruler sets (circles, squares, rectangles) are often shipped without retail packaging with the rulers stacked and taped together. This helps avoid damage to rulers in shipping. When sets are shipped in the loose packaging the rulers sometimes shift so one ruler is partially over another one and they can break in the sorting equipment.

The Circle Rulers by Lori Holt of Bee in my Bonnet is great for rotary cutting or template tracing.
