How to Get Accurate Half-Square Triangles

Do you have problems getting accurate half-square triangles? I’ve found a tool that really helps me to get precise half-square triangles. Let me tell you about it.

There are various methods to make a half-square triangle and I’ve tried just about every one – and still wasn’t pleased with the results. I love the look of half-square triangle designs, but didn’t like my results when I used them in my projects. I’ve finally found the perfect tool to give me accurate half-square triangles every time: the Tucker Trimmer.

The Tucker Trimmer by Studio 180 Design is an acrylic tool that comes in several sizes but the one I use the most is the Tucker Trimmer 1. You can make half-square triangles from 1” to 6” with this particular size of the Tucker Trimmer. Since I usually make small half-square triangles, this size works well for me.

The Tucker Trimmers can be used by right and left handed quilters and instructions are given for both. You can make half-square triangles in whole number sizes (1”, 2”, etc.) or in fractions (1½”, 2½”, etc.). I like it when a tool can be used for a variety of sizes as this makes it very practical and eliminates the need for purchasing a tool for every size.

The idea behind the Tucker Trimmers is that you make a half-square triangle a little bit bigger than you want the actual size to be and then you trim it down to the desired size. For example, if I want a 2½” half-square triangle, I might be starting out with one that is 2¾”. Yes, you will be cutting a little bit off each side, but this is how you get that super precise half-square triangle that will make such a difference in your project.
