What to cut for one block

A 12″ finished block measures 12½″ 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.

Templates. Pieces marked “cut with template” aren’t a shape a straight ruler cuts: cut the size given, then trim it to the template’s shape. Quarter Inch prints Triangles’s templates at true size with Quilter.

How it’s sewn

For the 6″ block. Choose another size above and these steps follow it.

Make 4 half-square triangle units
Sew a Dark C triangle to a Background C triangle along their long edges. Press toward the Dark. Each measures 1½″ (1″ finished).
Make 4 flying geese units

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 7 sections (A, B, C, D, E, F and G), 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 an intermediate block: 43 pieces in 4 different shapes and 20 points to match. Take it slowly and pin the points. We work the level out from the block’s own geometry, never by eye.
