hello@quarterinch.app
What size should I make it?
Its 2 × 2 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 4″, 7″, 8″, 10″, 14″, 15″, 16″ 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 2 sections (A and B), 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 a first-quilt block: 6 pieces in 2 different shapes and 1 point to match. Nothing in it curves or has to be set in. We work the level out from the block’s own geometry, never by eye.
