Double Clamshell + Straight Quilting Template
Double Clam + Straight template is laser cut from 5 mm acrylic and laser engraved on the back to reduce parallax error and enhance accuracy.
The clamshell (half circle) on top is 3″outside diameter to create half circle(clamshell) in 3 1/2″and the one on the bottom is 2 1/2″inside diameter creating a half circle (clamshell) with 2″diameter. The straight edge with stopper on both ends is for making stitch in the ditch easily and accurately,
This template will allow quilters to create a number of different shapes or designs on both long arm quilting machines or home sewing machines, using a special rule foot on their machine.
It is also much easier to draw inside the shape than around the outer edge and the 1/4″ increment lines help make echo lines with the same template.
