Quilt block

Broken Dishes quilt block

Four half-square triangles arranged so the diagonals mirror instead of rotate, producing a jagged zigzag rather than a spiral.

Also known as Broken Dish.

Broken Dishes is the pinwheel's sibling: identical pieces, different arrangement, completely different read. The name belongs to the large family of homely nineteenth-century block names drawn from kitchen and farm life, alongside Churn Dash, Monkey Wrench and Bear's Paw.

Broken Dishes cutting chart

Cut sizes include a ¼″ seam allowance: ½″ on squares and rectangles, ⅞″ on half-square triangles, and 1¼″ on quarter-square triangles. Pick a finished block size:

How it goes together

Four HSTs again, but arranged in mirrored pairs. Because the diagonals oppose each other, the block reads as broken shards rather than motion.

Tips

  • Lay all four units out before sewing — the difference between this and a pinwheel is one rotated unit.
  • At small scale and in scrappy fabrics it makes a superb allover filler.
  • Press seams in opposite directions between the two rows so the centre nests.

How much fabric for a Broken Dishes quilt?

Yardage for a whole quilt of Broken Dishes blocks, computed the way the studio does it — every piece packed across a 40″ usable width with 10% added for waste.

Blocks set edge to edge at 12″ finished, no sashing or borders. Change any of that in the studio and the numbers update.

What it looks like in a quilt

A single block only tells you half the story. Set sixteen of them together and the secondary pattern appears where the blocks touch:

Broken Dishes questions

What is the difference between Broken Dishes and Pinwheel?

The pieces are identical — four half-square triangles. In a pinwheel all four rotate the same direction; in Broken Dishes they mirror, which kills the spin and creates a zigzag.

Change one thing and every number follows

Resize the block, swap a fabric, add sashing — the cutting list and the yardage recalculate as you go. No spreadsheet, no re-doing the math.
