The clamshell tool is used for making arcs or an all-over 
clamshell pattern. It has different sizes on all four sides. 
1”, 2”, 3”, and 4”. 

Clamshell Pattern Fill 

Start with a horizontal guideline or seam. Align the etched line on the template to your guideline, and 

sew from one end to the other. 

If you are using the template(s) to quilt around (such as a longarm 

machine, or high shank home machine), you must use the 1/4” acrylic 

thickness. 

*If you are on a low shank home machine, 

you must use 3/16” acrylic thickness. If you are on a machine that 

is stationary, you may find it helpful to put some type of agent such 

as Grip Stop Dots or spray adhesive on the templates. Before 

using, peel any film/paper masking from the templates so you can 
see through the clear plastic.

 

*Note:

1)

 When using the template(s) you must have a ruler foot on your machine 

as well as a base (such as an extension table or ruler base).

2)

 When using the template(s) you will be stitching a 1/2” larger (the 

width of your foot), or 1/4” wider if only using a portion of the template 

(the distance from your needle to the outer edge of your foot).
