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 Criss Cross’s templates at true size with Quilter.

How it’s sewn

For the 12″ block. Choose another size above and these steps follow it.

  1. Add a corner square

    Lay the Medium B square on the corner, right sides together, and sew corner to corner across it. Trim ¼″ beyond the seam and press toward the corner. Each measures 3½″ (3″ finished).

  2. Add 5 corner triangles

    Sew the Medium F triangle across the corner, along its long edge, and press toward the triangle.

  3. Add 3 corner triangles

    Sew the Medium F triangle across the corner, along its long edge, and press toward the triangle. Each measures 3½″ (3″ finished).

  4. Add 3 corner triangles

    Sew the Background H triangle across the corner, along its long edge, and press toward the triangle.

  5. Make 1 section

    Sew the two parts together along the diagonal seam: Medium G piece to Background I piece. Press the seam to one side.

  6. Add 4 corner triangles

    Sew the Dark C triangle across the corner, along its long edge, and press toward the triangle.

  7. Make 1 section

    Sew the two parts together along the diagonal seam. Press the seam to one side.

  8. Add a corner triangle

    Sew the Background H triangle across the corner, along its long edge, and press toward the triangle.

  9. Make 1 section, 6½″ × 3½″

    Sew the two parts together along the diagonal seam. Press the seam to one side. Each measures 6½″ × 3½″ (6″ × 3″ finished).

  10. Make 3 sections

    Sew the two parts together along the diagonal seam. Press the seam to one side.

  11. Make 1 section

    Sew the two parts together along the diagonal seam. Press the seam to one side.

  12. Add 3 corner triangles

  14. 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.

  15. 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 12½″ (12″ finished).

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?

Yes. It splits into 11 sections (A, B, C, D, E, F, G, H, I, J and K), 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: 37 pieces in 7 different shapes and 24 points to match. Take it slowly and pin the points. We work the level out from the block’s own geometry, never by eye.
