Inputs

Sizes are computed from these fixed inputs: wof (in) 42, seam (in) 0.25, target (in) 40, 48, size tol (in) 4. A different gauge or stock makes a different size; the counts do not change.

Brief

“Please make a crib-size quilt about 40 x 48 in of churn dash blocks in forest green and butter yellow on unbleached muslin, with a narrow green border.”

Checks

The counts, part sizes and placement were checked by computation on 29 September 2026 (verified on attempt 2); the piece has not yet been made by hand. If yours comes out differently, tell us and we will look at it.
