1) Make 5 Squares
a) Attach two S (purple) Additions to your 24" ruler. They extend the cutting edge by ½".
b) Cut strips, then turn them 90º to make squares.
The seam allowance is automatically included with the cut-out squares.
2) Make Four HSTs:
a) Attach two H (green) Additions to your ruler. They extend the cutting edge by 0.854".
b) Cut strips. Then, turn them 90º to make squares.
c) Cut squares in half.
The seam allowance is automatically included with the cut-out squares.
Trim the Triangle Points
Using the Prep-Tool
Align the Prep-Tool with the short sides
of the half-square triangles.
3) Make Eight QSTs
a) Attach two Q (red) Addition to your ruler. They extend the cutting edge by 1.207".
b) Cut strips. Then, turn them 90º to make squares.
c) Cut squares in quarters.
The seam allowance is automatically included with the cut-out squares.
After sewing the pieces together, your block will measure 6 1/2". You’ll always have the extra 1/4” needed to sew the pieces, rows, or blocks together.
Trim the Triangle Points
Using the Prep-Tool
Align the Prep-Tool with the long sides
of the quarter-square triangles.
Seam Allowance Additions not only simplify the complex math of seam allowances, but they also help you make triangles more accurately than using a ruler alone. Click here to learn more about seam allowances for triangles.
4) Sew the Pieces Together
How to sew the triangles together
There are 3 combinations of triangle squares:
Made of 2 HSTs
Made of 1 HST and 2 QSTs
Made of 4 QSTs
Double Friendship Star includes
3-Part Triangle Squares
How to Sew 3-Part Squares:
1) Line 2 QSTs up right sides together & sew.
2) Align the two sewn QSTs with an HST and sew them together.
3) Press them open with the seam to the dark side.
2-Part Triangle Squares:
An example block that contains

scant 1/4" seam allowance.
Press them open with
the seam to the dark,
purple side.
4-Part Triangle Squares:
An example block that contains
4-part triangle squares

right sides together & sew.

QSTs up together & sew.
Press them open.
Sew Accurately!
To make sure the points on your triangles stay pointy in your finished block,
sew them together with a scant - slightly less than - ¼” seam allowance.

What is a Scant 1/4"?
A scant ¼" is a seam allowance sewn slightly less than a full ¼".
This compensates for the thread and the fold, so the finished seam measures an accurate ¼". Your pieces will match and your points will be sharp.
Without a scant 1/4", your seams will end up wider than a full 1/4". The discrepancy can add up, so that your finished quilts can end up a little smaller than intended.
