Cross Stitch Pattern Generator turns your own photo, a pet, a portrait, a house or a child's drawing, into a printable cross stitch chart. You pick the stitch count, the fabric count and how many thread colors to use, and every color is matched to a DMC floss number so the key matches what you buy in the shop. The printable PDF has a symbol chart, a color key with skein counts and a floss shopping list, and large patterns are split across pages with overlap. The preview is free in the browser with no account; the printable PDF is 5.99 dollars per photo and re-exports of the same photo are free. Uploaded photos are deleted within 24 hours.
I lost an evening to a pattern maker that gave 40 shades of grey and no thread numbers, so I built one that decides what to throw away and tells you what floss to buy.
