Lady of the Lake quilt block
A big half-square triangle unit in the center, ringed by sixteen small ones.
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.

Between the lines. Lady of the Lake cuts cleanly at 5″ or 7½″. At 6″ its half-square triangles' short sides are 1¹⁄₅″, so they need templates.

hello@quarterinch.app
What size should I make it?
On its 5 × 5 grid, 6″, 9″ and 12″ put some pieces between the ⅛″ marks, so they need templates. It cuts cleanly at 10″ or 12½″.
Can I paper piece it?
Yes. It splits into 4 sections (A, B, C and D), 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: 34 pieces in 2 different shapes and 12 points to match. Take it slowly and pin the points. We work the level out from the block’s own geometry, never by eye.
