📷 Photo to Pattern
Take a photo of any knitted or crocheted garment — a jumper, cardigan, accessory. AI identifies the construction, style, and stitch details, then generates a full pattern for you to recreate it.
Step 1 — Photograph the Garment
📌 Tips for best results: Lay the garment flat on a light surface. Include all key details — neckline, cuffs, any stitch pattern. A ruler or tape measure in shot helps AI estimate scale.
