Product Overview

New!! This template came to me as I've been making the 3D for a month. 

This little gadget has all the dimensions of 4 sizes of the 3D or Octagon style mask, which is THE most comfortable reusable mask to date. 

This also is perfect for precisely shaping your placemats. 4 sizes of corner cuts.

The Template will let you make 4 different sizes. I've included an optional sandpaper stick-on that you can cut into small pieces to place on the back so it won't slide around on your fabric.

There's enough to cut a few pieces for the back of your rulers too. Do NOT use your good scissors to cut the sandpaper as I don't know if it causes any damage to your scissors. It's grainy, so I cut them with my old gardening scissors. But, I have to tell you, it does the trick! No more sliding around. If you use some to stick on your ruler to cut your rectangles, you will be happy with the results.

    Acrylic Corner Cutter

    Posted by Sylvia Strain on Apr 26th 2021

    Looooove this little cutter!!!!! Exactly what I needed for my 3D masks. Saves me lots of positioning time. I can literally cut all over my well used mat which gives it a break. Ten stars for this Acrylic Corner Cutter. You will be so happy you got this!
