TRY ASKING
"How big should a queen quilt be for a 14 in mattress?" "Cut sizes for 3 in HSTs, 8 at a time." "Yardage for this pattern at twin size."

HONEST ABOUT WHAT IT DOES
• Working shown: Every cut size and yardage comes with the calculation.
• Sensible rounding: Cut sizes to the nearest 1/8 in, yardage up to the next 1/8 yd, with a margin.
• Your assumptions: Usable width, seam allowance and finishing method stated up front, and easy to change.
• Respects designers: It helps you resize and calculate for your own use, without copying a pattern's instructions.

HOW IT WORKS
1. Download your 3 files right after purchase (2 skill ZIPs and the Start Here PDF).
2. In Claude, open Customize, then Skills, click +, choose Upload a skill and pick each ZIP. Keep them zipped.
3. Start a new chat and ask: "I want to make a queen quilt with 12 inch blocks. Plan the size, blocks and yardage."

WHAT YOU NEED
• A Claude account (claude.ai). The free plan works: turn on code execution in Settings, Capabilities.

AI DISCLOSURE

GOOD TO KNOW
Quarter Inch gives quilt planning calculations based on the information you provide. Fabric widths, shrinkage and individual cutting and sewing vary, so check measurements before you cut.
