Indian Trails quilt block
Four large half-square triangles turn round the center, each edged with a sawtooth of small triangles like a trail through the woods.
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 8 × 8 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 8 sections (A, B, C, D, E, F, G and H), 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: 60 pieces in 3 different shapes and 28 points to match. Take it slowly and pin the points. We work the level out from the block’s own geometry, never by eye.
