Simplify Cutting a Polymer Clay Square

Cutting clay with blade on graph paper

Using a perfectly straight polymer clay blade is one way to get a straight cut.

Use a ruler and graph paper to cut a square from polymer clay.

Have you ever struggled to cut a polymer clay square or rectangle? One that has nice straight sides and perfect corners? In search of a solution, I used to make a paper pattern that I placed on top of the clay, but that presented two problems: 1) I couldn’t see the clay area I was cutting, and 2) the paper wanted to jump when I made the cut.

For a time, I used plastic guides like quilters use. The problem was that I’d have to lift the clay at some point to place it on a curing tile, and that was hard to do without distorting it.

I started using graph paper as guides a long time ago. You can print them free from the Incompetech.com web site. You can specify the size of the squares and weight of the lines.

If I’m cutting a large square, I mark the measurements on the graph paper. For smaller squares, I can readily see the guidelines.

There are two ways to cut:
1. Use a perfectly straight polymer clay blade and look straight down to align the blade with the guidelines. You may need to stand. Grip the blade close to the clay’s edges, and pull away from the edges to put tension on the blade. This will keep it from warping when you make the cut.

2. Align a metal ruler with the guidelines. Be sure to place the ruler on the clay you plan to discard. You don’t want to leave a ruler mark on your clay square. Hold the ruler firmly in place and cut along it with a craft knife.

You can leave the polymer clay square on the paper and move both to a ceramic tile for curing.

    Thanks for the tip. I’m going to print out grids.
