AI Knitting and Crochet Helper for Claude | Gauge Calculator and Pattern Resizing | Digital Download

Make it fit. Have enough yarn. Every time.

Cast On turns Claude into the friend at knit night who's great at math. Turn your swatch into real numbers, resize patterns, space increases evenly, swap yarns safely, work out how many skeins to buy, and design simple hats, socks and blankets that fit.

This is a digital download of AI skills for Claude, the AI assistant by Anthropic. A skill is a set of expert instructions you add to your own Claude account. Nothing to print, no app to learn.

WHAT'S INCLUDED
• Gauge math and finished sizes
• Pattern resizing
• Evenly spaced increases and decreases
• Yarn substitution and skein counts
• Simple pattern design
• Abbreviations, charts and fixes
• Project tracking
• Updates for a year
• Bonus: the Gauge Calculator skill
• Start Here guide (PDF) with two-minute setup steps

TRY ASKING
"My gauge is 18 sts and the pattern says 20. Now what?" "Design a slouchy hat in worsted." "How many skeins of this DK?"

HONEST ABOUT WHAT IT DOES
• Working shown: Every count, measurement and yardage comes with the calculation.
• Pattern multiples respected: Counts rounded to fit the rib or stitch repeat, and it tells you which way it rounded.
• Your terms: US or UK crochet terms, knit or crochet, inches or centimeters.
• Respects designers: Helps you resize for your own use without copying a pattern's text or charts.

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: "My swatch is 18 stitches over 4 inches and my pattern wants 20. Help me get this sweater to fit."

WHAT YOU NEED
• A Claude account (claude.ai). The free plan works: turn on code execution in Settings, Capabilities.
• This is a digital file. No physical item will be shipped.

AI DISCLOSURE
I designed and wrote these skills with AI assistance, under my own creative direction and review. When you use them, Claude (an AI) writes the answers.

GOOD TO KNOW
Cast On gives knitting and crochet calculations and guidance based on the information you provide. Yarns, tension and blocking vary, so swatch and measure before committing to a project.
