Triangle Puzzle quilt block
A five-patch star: long star points on each side and half-square triangles beside dark squares make the arms, round a dark center square with plain 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
4 corner squares, 4 squares and 12 triangles
- D4 rectangles 1⅞″ × 1¾″then cut with template D
- A8 squares 1¾″then cut with template A
- B8 squares 1¾″then cut with template B
Dark · Navy in the picture
1 center square, 4 squares, 8 triangles and 8 star points
- A5 squares 1¾″then cut with template A
- B8 squares 1¾″then cut with template B
- C8 rectangles 1¾″ × 1¼″then cut with template C
Between the lines. Triangle Puzzle cuts cleanly at 5″ or 7½″. At 6″ its half-square triangles' short sides are 1¹⁄₅″, so they need templates.

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.

How it’s sewn
For the 6″ block. Choose another size above and these steps follow it.
- Make 8 half-square triangle units
Sew a Dark B triangle to a Background B triangle along their long edges. Press toward the Dark. Its size isn’t on the ⅛″ ruler at this block size, so sew it as cut and don’t trim it.
- Add 4 corner triangles
Sew the Background D triangle across the corner, along its long edge, and press toward the triangle.
- Add 4 corner triangles
Sew the Dark C triangle across the corner, along its long edge, and press toward the triangle. Its size isn’t on the ⅛″ ruler at this block size, so sew it as cut and don’t trim it.
- Sew the units and pieces into 5 rows
Lay out the units and pieces as in the picture and sew them into 5 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 5 rows, matching and nesting the seams where they meet. Press the long seams open or to one side. The block measures 6½″ (6″ finished).

hello@quarterinch.app
What size should I make it?
On its 10 × 10 grid, 6″, 9″ and 12″ put some pieces between the ⅛″ marks, so they need templates. It cuts cleanly at 10″ or 12½″.
Can I paper piece it?
Yes. It splits into 6 sections (A, B, C, D, E and F), 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: 41 pieces in 4 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.
