makes the Wonder Cut Ruler so different?
The answer is simple. It's a method we call "pre-sewing." It's reverse of the method most rulers use. You sew first, and then cut.
a picture of the Wonder Cut Ruler. You'll notice one side of the
is labeled "Cut along this edge".
This edge is where you will cut your fabric with your rotary cutter. The long lines of the ruler indicate the unfinished size of your half-square triangle and the width you need to cut your fabric.
IMPORTANT: Before you start, you need to know this: If you cut your strips on the straight grain of the fabric, your finished half-square triangle edges will be on the bias. If you start with your strips cut on the bias, your finished half-square triangle edges will not be on the bias.
Ready? Here we go ... Lots of pictures for you to look at.
the long cutting lines (horizontal lines), cut the desired size for
your unfinished half-square triangle from two fabrics.
2) Lay the two strips right sides together.
3) Sew both long
sides of the fabric strips together with a 1/4" seam. You will be
a "tube" of fabric. The sample shown below is sewn with red
so that you can see the stitches in the picture. For best
we recommend a neutral or matching thread.
4) Using the
diagonal lines of the ruler, lay the line for the desired size of the
triangle along one long edge of fabric.
5) Cut along
of the ruler.
6) Turn the
fabric tube over and align the ruler with the edge of the fabric and
make one cut.
You have now
half-square triangles! :)
Continue this process down the length of the fabric tube. Take a moment to trim your fabric "tails" and then gently press the seams to the darker fabric.
There you have it! Wonder Cut half-square triangles!
