1979 changed quilting forever.
But no one told you how.
And it's affecting
your seam allowances today.

Seam Allowance Story:

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?

When quilters switched to
rulers and rotary cutters,
something important got lost.

That is because
Quilting rulers only have
markings in ⅛″ increments.

Rulers work for straight cuts like
squares and rectangles…

But it does not match
the real math needed for
TRIANGLES,
which require diagonal cuts.

To use a quilting ruler,
quilters had to abandon
the real math needed for
TRIANGLES,
which require diagonal cuts.

• 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:

Only a few technical educators
were aware of the shift.
Most never knew or ignored it.
So the wrong measurements
became the standard.
Books repeated them.

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

without knowing why.

Even perfect cutting & sewing
still produce
incorrectly sized blocks.

It’s not your fault.
It’s the ruler.

If you already know how important
it is to achieve accuracy by
sewing a scant ¼” seam,
which is only 1 to 2 thread widths smaller than a Full ¼”, then
The discrepancies in making HSTs (1/32") and QSTs (1/16") are ridiculously greater.

This is why
Your triangles turn out larger than squares. Also, half and quarter square triangles in the same block, like in
Flying Geese or
Double Friendship Star blocks,
never match each other.

Many quilters compensate for these discrepancies by oversizing their triangles and trimming them later to the correct size, which is time-consuming, a waste of fabric, and, most of all, pesky and frustrating.

Some quilters avoid making quilts with triangles.

This why
We designed:
Seam Allowance Additions™
for quilters like you
to correct this measurement problem automatically.

They attach to the rulers you already have and add the exact seam allowance right at the edge:

+1/2″ for squares

+0.854″ for HSTs
+1.207″ for QSTs

Sure,
you could buy individual dies or templates for every triangle size, but that gets expensive fast, and fabric is expensive enough!

Here's the Solution! 

Super Easy FSQ Set with
Seam Allowance Additions

by Guidelines4Quilting

 
1) Add the accurate seam allowances for squares, half-square triangles, and quarter-square triangles.

2) Allow you to make any quilt block in any size, simply by using just one measurement, which is
the Finished Patch Size.

3) Our Color-Coded System shows which Addition to use for making many popular blocks, including more complex ones.

4) Additional tools included in the set prevent your rulers from slipping and ensure precise cutting and sewing.

Perfect for:

✔ Beginners to advanced quilters

✔ Ruler and rotary cutter users
✔ Anyone frustrated with trimming
✔ Quilters who want accurate piecing & block matching
✔ Anyone who wants to make 9 and 16-patch blocks, Flying Geese, Diamond-in-a-Square, or more complex blocks.

"...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!"

The S Addition (purple) adds
1/2" for squares

The H (green) Addition adds
0.854" for HSTs

The Q Addition (red) adds
1.207" for QSTs
