New Waterwheel quilt block
A nine-patch centre, four three-strip side units and four large half-square triangles 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 large triangles, 8 strips and 5 squares
- B2 squares 2⅞″cut once on the diagonal
- A8 rectangles 2½″ × 1¼″then cut with template A
- C5 squares 1¼″then cut with template C
Dark · Navy in the picture
4 large triangles, 4 strips and 4 squares
- B2 squares 2⅞″cut once on the diagonal
- A4 rectangles 2½″ × 1¼″then cut with template A
- C4 squares 1¼″then cut with template C
Between the lines. New Waterwheel cuts cleanly at 4½″ or 9″. At 6″ its rectangles are ⅔″ wide, 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 4 half-square triangle units
Sew a Dark B triangle to a Background B triangle along their long edges. Press toward the Dark. Each measures 2½″ (2″ finished).
- Make 4 rail units
Sew the Background A and Dark A rectangles together along their long edges. Press toward the Dark. Each measures 2½″ (2″ finished).
- Make 2 sections
Sew 2 Background C pieces and a Dark C piece together in a row. Press the seams to one side. Its size isn’t on the ⅛″ ruler at this block size, so sew it as cut and don’t trim it.
- Make 1 section
Sew 2 Dark C pieces and a Background C piece together in a row. Press the seams to one side. Its size isn’t on the ⅛″ ruler at this block size, so sew it as cut and don’t trim it.
- Make 1 section, 2½″
Sew 3 sections together in a column. Press the seams to one side. 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).

Questions

hello@quarterinch.app
What size should I make it?
At 9″ every piece measures with a ruler. On its 9 × 9 grid, 6″ and 12″ put some pieces between the ⅛″ marks, so they need templates. It cuts cleanly at 9″ or 13½″.
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 3 different shapes. Take it slowly and check each piece against the list. We work the level out from the block’s own geometry, never by eye.
