Hey Everyone, welcome back to Cool Tool Thursday.

I found another ruler at the bottom of my ruler drawer that I have never used. I do recall buying this one when I was at an Empty Spools Seminar and still living in Australia so that was a few years ago.

As the name OmniArc suggests, one can cut an arc with this ruler.

Several pieces cut from one square of fabric folded in quarters

A single layer of fabric gives a quarter of a circle.

A double fold of fabric yields a half circle. A full circle is cut using the fabric folded in quarters.

A quadruple fold of fabric is needed to cut circles and rings.

A square of fabric folded in quarters will give you circles and rings – even a bullseye

A 45 mm rotary cutter is needed – the smaller cutters will not fit in the groove as they are too small. The ruler cuts from 4 inch to 12 inch circles.

How it works

Place the black lines at the left hand corner of the fabric. The arc will start below the fabric and end beyond the fabric. If you are folding the fabric for half and full circles, ensure you place the folds on the bottom and/or left sides of the guide lines.

Place the rotary cutter in the groove and cut the fabric along the groove.

Open up the fabric to reveal the circle.

One complete circle

If you wanted to fuse these circles to the quilt then I suggest adding fusible of the light variety such as misty fuse to the back of the fabric first before cutting so that the edge of the circle has the glue in place after cutting.

Certainly a great way to cut precise circles, rings and arcs.

A variety of pieces cut with the OmniArc

There you have it. The Omnigrid OmniArc is definitely a handy tool that full-fills it’s promise of easy, accurate cutting of circles and parts thereof. Drawbacks are few – if you need a size that isn’t provided in the slots you’ll have to do some mental and finger gymnastics.

Happy Quilting!
