Komfort KUT Slash-N-Circle Ruler cuts perfect circles for applique quilts

Yesterday, I showed you the benefits of using the SURElight M4T LED Desk Lamp. Over the next three days, I’m going to show you fun and easy ways to make quilt blocks using the Komfort KUT Slash-N-Circle Ruler 9⅞” x12½“.

When I first saw the Komfort KUT Slash-N-Circle Ruler, I knew that I found a ruler that I was going to enjoy using. So, today, we’re going to use this ruler to cut out full circles, half-circles, and quarter-circles to make a 12″ quilt block.

With the Komfort KUT Slash-N-Circle Ruler, you can cut circles in the following sizes: 5cm, 8cm, 11cm, 14cm, 17cm, 20cm, and 23cm.

For this project, I found that the best rotary cutter size to use is the 18mm Komfort KUT Rotary Cutter.

As I still have some HEATNBOND Lite Iron-On Adhesive Sheets – 17″ x 1yd left from my February post, I’ll be using it again for our projects this week.

I made a 12” block using quarter, half, and full circles so that I can better demonstrate how to use the Slash-N-Circle Ruler.

Therefore, precut pieces of HEATNBOND Lite in the following sizes:

  • 3½” x 3½” for the full circles, which is slightly larger than the 8cm circle you make with the ruler
  • 2″ x 3½” for the half circles
  • 2″ x 2″ for the quarter circles

Fuse these pieces of HEATNBOND Lite to pieces of fabrics.

On the piece of fabric that you use for the full circle, draw a line in the center. On the fabric that you use for the quarter circles, draw two sides of a square.

Prepared piece of fabric for cutting

To cut out a full circle, first fold the fabric on the drawn line. Align the red line of the Slash-N-Circle Ruler to the fold. Use the ¾” Komfort KUT Rotary Cutter to cut out the circle.

To cut out a semi-circle, align the dotted line to the bottom of the fabric. Using the dotted line ensures that there is a seam allowance. If a seam allowance is not necessary, then cut using the solid red line.

Cutting out a semi circle

The method to cut out the quarter circles is the same as the method you use to cut out semi-circles.

Place the dotted line on the penciled line to cut a quarter circle.

On the background fabric, draw a 12” square to help with the placement of the circles, and affix the circles to the fabric.

I had a fun day cutting out circles for this modern-looking quilt block. Think of all the creative ways you can use the Komfort KUT Slash-N-Circle Ruler, available at your local quilting store.

Come back tomorrow to see me demonstrate an easy and simple way to use the Komfort KUT Slash-N-Circle Ruler to help draw quilting lines.

What a clever tool! I really love the circles in shades of yellow to orange on the white background.

I have seen these rulers in the store and wondered how they were used. Thanks for the great tutorial!
