Quilting Tutorial: How to Use the Omnigrid On-Point Ruler

Because a quilting tool that takes math out of the equation is very nice indeed.

Squares on point in borders……… Hmmmm.

YIKES! Does the thought of all that math make your head want to explode? This number times 1.414 plus that number and on and on and on? And then after all that, it still doesn’t fit anyway.

Well, despair no more—the Omnigrip™ On-Point ruler takes ALL that nasty old math out of the equation and gives us back all those on-point possibilities. Now you can cut squares that will measure nice and neat across the diagonal so you can set them on point in borders or blocks. Is your brain whirling with ideas yet?

Okay so how does this work you ask. Well, take a look at this pretty little quilt. The on-point border needs 11 squares that measure 4” finished size on the diagonal to fit its 44” length.

That diagonal measurement is all you need to know.

Using the On-Point ruler, you’ll cut strips at the 4” mark just like you would cut any strip. Yup—It’s that simple. Whatever you want the diagonal measurement to be is the mark you use to cut on the ruler. Look Ma, no math!

And when I say no math, I mean it. Not even for seam allowances. This fine tool has a 1/2″ margin all the way around for those 1/4″ seam allowances. So, no math really, really, really means no math.

Now, before we chug along any further, take a look again at the grid on the ruler. I’ll bet you’re thinking it looks pretty much like a regular ruler where the grids measure 1″ from side-to-side all the way across the ruler.

Well, what makes this such a cool tool is that those grids actually measure 1″ across their diagonals not from side-to-side. Pretty tricky, eh?

I can hear your hand slapping your forehead as you realize “Gee so that’s how it measures diagonals!” And that, my dear quilters, is why it says the measurements are non-standard!

Zap— trim the selvedges from the strip edges and cut squares from the strip using the 4” mark.

Bam—you’re done!

So, remember, when you want simple squares set on point in a border or a block, decide what you want the diagonal measurement to be. Then cut strips and squares using that same mark on the On-Point ruler. Simple as Pi.

The On-Point ruler was designed by Donna Lynn Thomas because she was tired of the measuring limitations of regular rulers. She was also alarmed at the rate of cardiac arrests in her students when trying to explain the math needed to come up with diagonal measurements.

Find Donna online here or on Facebook as Donna Lynn Thomas Quilter. Also, keep an eye out for her new book, “On-Point Patchwork,” that will be published in the fall of 2013 by Martingale; it will be loaded with patterns using the ruler.
