Aunt Dinah quilt block
A nine-patch of hourglass units and half-square triangle units round a plain center, with dark squares in the corners.
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.
Background · Snow in the picture
1 square and 16 triangles
- D1 square 3¼″cut twice on the diagonals
- B2 squares 2⅞″cut once on the diagonal
- E1 square 2½″
- C4 squares 1⅞″cut once on the diagonal
Dark · Navy in the picture
4 squares and 8 triangles
- D1 square 3¼″cut twice on the diagonals
- B2 squares 2⅞″cut once on the diagonal
- A4 squares 1½″
Worked out by @quarterinch/cutting · ¼″ seams included · strips cut across 42″ of usable width · the letters are the pieces the sewing steps name
A 9″ finished block measures 9½″ 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.

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 5 sections (A, B, C, D and E), 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: 29 pieces in 5 different shapes and 12 points to match. Take it slowly and pin the points. We work the level out from the block’s own geometry, never by eye.
