Card Trick quilt block
A nine-patch of half-square and quarter-square triangle units, set so four cards seem to overlap round the center.
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 large and 4 small triangles

- A2 squares 2⅞″cut once on the diagonal
Dark · Navy in the picture
4 large and 4 small triangles

How it’s sewn
For the 6″ block. Choose another size above and these steps follow it.
- Make 2 half-square triangle units: Dark and Background
Sew a Dark A triangle to a Background A triangle along their long edges. Press toward the Dark. Each measures 2½″ (2″ finished).
- Make 2 three-triangle units: Dark and Medium and Background
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).
- Make 2 half-square triangle units: Medium and Background
Sew a Medium A triangle to a Background A triangle along their long edges. Press toward the Medium. Each measures 2½″ (2″ finished).
- Make 2 three-triangle units: Medium and Dark and Background
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).
- Make 1 quarter-square triangle unit
Sew the Medium B and Dark B triangles together in pairs along a short edge, then join the pairs, matching the seams at the center. Press the last seam open. Each measures 2½″ (2″ finished).
- Sew the units into 3 rows
Lay out the units 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).
For the 9″ block. Choose another size above and these steps follow it.

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: 24 pieces in 2 different shapes and 9 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.
