Double Friendship Star quilt block
A nine-patch star of quarter-square triangle units, with a second star of half-square triangles turning inside it.
What to cut for one block
A 6″ finished block measures 6½″ before it’s sewn into a quilt. Each fabric’s yardage is the least that cuts its strips across the width of fabric, with a strip to spare for straightening.

How it’s sewn
For the 6″ block. Choose another size above and these steps follow it.
- Make 4 three-triangle units
Sew the two small triangles together along a short edge, then sew them to the large triangle, matching the point to the middle of its long edge. Press toward the large triangle. Each measures 2½″ (2″ finished).
- Sew the units and pieces into 3 rows
Lay out the units and pieces as in the picture and sew them into 3 rows. Press the seams in row 1 to the left, row 2 to the right, and so on, so they nest when the rows are joined.
- Join the rows
Join the 3 rows, matching and nesting the seams where they meet. Press the long seams open or to one side. The block measures 6½″ (6″ finished).

Questions
Short answers.

hello@quarterinch.app
What size should I make it?
Its 6 × 6 grid lands on the ⅛″ marks at 6″, 9″ and 12″, so every piece measures with a ruler at all three. It also cuts cleanly at 15″ and 18″. In Quarter Inch you can make it any size, and it says when a cut falls between the lines.
Can I paper piece it?
Yes. It splits into 4 sections (A, B, C and D), each sewn on its own paper in order and then joined with straight seams. In Quarter Inch, the Foundations tab prints its papers at true size (with Quilter).
Is it a good block for a beginner?
It’s a good block for a beginner: 17 pieces in 3 different shapes and 8 points to match. Nothing in it curves or has to be set in. We work the level out from the block’s own geometry, never by eye.
