Everything was cut with
Scissors & Templates,
Not Rulers & Rotary Cutters.

Quilters traced a 1/4" seam allowance
around every template.

It was tedious, but
Everything Used to Fit
Perfectly Back Then!

What Changed?

To use a quilting ruler,
quilters had to abandon
the real math needed for
TRIANGLES
Because
Quilting rulers only have
markings in 1/8″ increments.

• Your ruler forces you to add
  7/8" for half square triangles,
  which is almost 1/32" too much:
  

• Also, it forces you to add 1¼"
  for quarter square triangles,
  which is almost 1/16" too much:

So the wrong measurements
became the standard.
Books repeated them.

Patterns repeated them.
Teachers repeated them.
And quilters kept struggling

without knowing why.

It’s not your fault.
It’s the ruler.

The discrepancies in making HSTs (1/32") and QSTs (1/16") are extremely significant.

This is why
Your triangles turn out larger than squares. Also, half and quarter square triangles in the same block
never match each other.

Quilters oversize their triangles and trim them later to the correct size, which is time-consuming, a waste of fabric, pesky, and frustrating.

😢 Some quilters completely avoid making quilts with triangles.

This why
We designed:
Seam Allowance
Additions™

They attach to the rulers
you already have and add
the exact seam allowances:

+1/2″ for squares

+0.854″ for HSTs
+1.207″ for QSTs

"...I've been quilting for fifteen years... You'd never believe I was a math major in college and have such trouble with the math of triangles in quilting!

No more! I experimented with the Guidelines and now I'll tackle more half-square and even quarter-square projects without worry!"
