W.C.T.U. quilt block
Four dark corner units with points on two sides sit around a background centre crossed by a dark diagonal strip.
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.

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 12 sections (A, B, C, D, E, F, G, H, I, J, K and L), 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 advanced block: 174 pieces in 2 different shapes and 20 points to match. Practise the hard seams on scraps first. We work the level out from the block’s own geometry, never by eye.
