Quick Quarter Ruler

Mark your half and quarter square triangles quick as a whistle!

Quick Quarter Ruler8" Quick Quarter Ruler

The Quick Quarter Ruler is the perfectly named quilting tool used by quilters to quickly and accurately mark quarter inch stitching lines for half- and quarter-square triangle units.

The tool can be used for either the Quick Pieced or 8 at a Time methods for making half squares triangles (HST).

Since quarter square triangles are nothing but 2 pair of HSTs, you can use it to mark Quick Pieced Quarter Square Triangles.

Last but not least—use it, too, for our Four at a Time, No-Waste Flying Geese units.

(Click on any of the preceding underlined techniques for more information on that particular method.)

Pros and Cons

The Quick Quarter works exactly as advertised.

It's benefits are:

  • You position it only once to mark both sewing lines on each pair of squares
  • You sew on the drawn line instead of 1/4" away from a drawn line

To mark both lines with a standard quilt ruler, you re-position it for EACH line or twice per square. For marking, say, 100 squares, that adds up to a big time savings. YOUR time.

On the other hand, this is another ruler to store whose job can be replicated with your regular rotary ruler.

You may find it easier to stitch on the drawn line with an open toe applique foot. This foot may or may not already be in your accessory case.

How to Use the Quick Quarter Ruler

On the back side of a square patch, line up the center notches in the ruler with a pair of diagonal corners.

Mark along each side of the ruler. I prefer to use a mechanical pencil because the line is always the same size. Hold the pencil at an angle so that the lead is right next to the ruler.

Sometimes the pencil wants to grab and pull on the fabric. If it happens to you, try marking each line from the center out to minimize or eliminate this problem.

You may choose to mark in the notches, too. This notched line represents the cutting line.

After marking, your patch looks like this.

Now layer your patches right sides together and stitch on the drawn lines.

If you are sewing many half square triangles, make your work easier by alternating between the two different line positions.

In the photo below, the left line (as you sit at your machine) was stitched and I am just getting ready to stitch on the right line of the next pair of patches. (The arrows point to the right line on each.)

Notice how nicely the patches snug up to each other—much less chance of your sewing machine 'eating' the edge as you stitch.

Press the patch flat to set the seams, then cut the square in two between the two stitching lines—or on the dashed line if you drew it.

Finally, press the patch open with the seam allowances to the dark (traditional), or light (possibly to reduce bulk) or open (to reduce bulk or for preference). The choice depends on your preferences and needs.

Trim to size if necessary.

Purchase a Quick Quarter Ruler

In the photos above, my trusty Quick Quarter is yellow (I've been quilting almost since dinosaurs walked the Earth). These days they are made out of a blue plastic.

They come in two sizes—8" and 12" inch. Mine is eight inches long and I've never had need of a longer one.

An eight inch ruler works for squares up to 5-1/2"; the twelve inch spans the diagonal of squares cut up to 8-1/2" x 8-1/2".
