Multi Clamshell Ruler

looks like it will work. Have not tried it yet

Good for long arming, however the shapes are quite small and these rulers tend to shift. I had to purchase additional grips to keep it in place. Also, they crack easily if dropped. I find the smallest size is too small to make me want to use it in any custom quilting. I have used the 2 largest sides. I purchased this thinking that it was almost like a 4in one, however I wasnt overly impressed.

Great

This template is great! The size makes it easy to hold in place and the placement lines make aligning it easy. I love having 4 different sizes in one tool.

This looks very handy to use.

This will help me make uniform clamshells of various sizes.

This was easy to use on a home sewing machine for ruler quilting. It was great for exactly the clam shells that I wanted it for.

MADE TO USE WITH HIGHSHANK MACHINE WHICH IS GREAT.

Havent used it yet, but looks like itll be good.
