The QPC #20 makes quick work of larger blocks. Measuring 13 inches from end to end, it can span a 12 inch block.
This high quality curved template from the Quilted Pineapple is a joy to work with! The ruler has the same curve as part of a 20 inch circle. It has the same curve on the concave and convex sides, so you can easily use it at different positions around your machine's ruler foot. Etched lines are accurately marked and are a uniform 1/4 inch spacing along the edge.
Great for long arm and high shank machines. In the accompanying image, a brand new one is on top, the one below has had the paper backing removed and you can see the markings more clearly. The QPC #15 does not come with the True Grip stickers shown on the lower ruler, but is highly recommended due to this ruler's length.
This ruler is also included in the QPC Full Set.
*Remove paper backing prior to use. Begin by peeling one corner and continue across the ruler.
