No more pesky formulas to remember! No triangle paper to remove!
Your Wonder Ruler quilting ruler is designed to cut squares and half- and quarter-square triangles. No paper to remove. No "magic number" to remember. All the cutting is based on the finished size of your triangle square unit.
The first thing you'll observe on these quilting rulers is that the grid lines do not extend to the edge of the acrylic square.
That's because all you need to remember is the finished size of the block or unit you wish to make. All the seam allowances are "outside the grid"!
A closer look reveals that the grid isn't quite centered. That's because three of the sides are used to cut three common, but different, patch shapes: squares, half square and quarter square triangles.
Notice there's a different symbol in three of the four corners of the Wonder Ruler. An empty square, a square halved by a diagonal line, and a square quartered by two diagonal lines.
There are two versions of the Wonder Ruler quilting ruler. One with a gird marked in 1/8" increments; the other with 1/6" increments. Both create patches for units up to a 10" finished size.
The basic steps are the same, regardless of what shape you are cutting.
To ensure the proper seam allowance is added, it's important to have the correct symbol in the upper right hand corner for the shape you are cutting:
And if you are left handed, then the symbol must be in the lower left corner so that the correct seam allowance is added.
That's it! No math! No magic numbers to remember with the Wonder Ruler quilting ruler!
This is the ONLY ruler on the market today that is marked in 1/6" and 1/3" increments making it the perfect tool for cutting fabric shapes for nine patch and thirty-six patch blocks.
ANY 9-patch quilt block is just a rotary cut away.
For example, in a recent block exchange, my bee-mates and I decided to exchange 4" finished blocks.
Great! Sounds like fun!
But if I wanted to make a block based on an even 9 patch grid, it was impossible to rotary cut. Each square needed to be 1-1/3" finished, cut at 1-5/6".
My rotary ruler doesn't have that mark. Does yours?
The 1/6" Wonder Ruler does!
Want to make a 5" nine patch? Just align the cut edge with the 1-2/3" line. To make a seven inch block, align the cut edge with the 2-1/3" line.
The Wonder Ruler quilting ruler also comes in an 1/8" version with the grid marked like our traditional quilting ruler in 1/8" and 1/4" increments.
...a video is even better. Watch Barbara Chojnacki (creator of Wonder Ruler quilting rulers) as she demonstrates cutting squares, half square and quarter square triangles.
