Nine Patch Frame quilt block
A centre square in a square of four triangles, framed on point by four dark trapezoids, with a corner piece and two small triangles filling each corner.
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.

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 Nine Patch Frame’s templates at true size with Quilter.

How it’s sewn
For the 6″ block. Choose another size above and these steps follow it.
- Add 4 corner triangles
Sew the Light C triangle across the corner, along its long edge, and press toward the triangle.
- Sew the set-in seams
These pieces meet where a straight seam can’t run right across, so they’re joined with set-in (Y) seams. Mark the ¼″ seam points at each piece’s corners. Sew each seam only from mark to mark, backstitching at both ends, so the seam allowances stay free; sew the two seams into the corner, then pivot and sew the last one. Press the allowances so they swirl round the point. The part measures 6½″ (6″ finished).
- Add 4 corner triangles
Sew the Light C triangle across the corner, along its long edge, and press toward the triangle.
- Make 1 section
Sew the two parts together along the diagonal seam. Press the seam to one side.
- Make 1 section
Sew the two parts together along the diagonal seam. Press the seam to one side.

hello@quarterinch.app
What size should I make it?
Its 12 × 12 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?
Not as drawn: it has set-in (Y) seams, where three seams meet and none runs straight through. Piece it with a rotary cutter and templates instead, as the cutting list above does.
Is it a good block for a beginner?
It’s an advanced block: 21 pieces in 5 different shapes, set-in (Y) seams and 16 points to match. Practise the hard seams on scraps first. We work the level out from the block’s own geometry, never by eye.
