Tools
| Tool | What it returns |
|---|---|
make_pattern_from_image | Converts a public PNG, JPEG or WebP image into a punch needle pattern with the website's pattern converter. Returns the pattern as a stitch grid preview, its colours and the yarn each colour needs in a fine-wool kit and a rug-wool kit. |
find_patterns | Lists the original punch needle patterns in the Punchneedle.ai library, filtered by theme and level. Each pattern shows its finished size, number of colours, level and preview image. |
get_pattern | Returns one library pattern with its size, colours, making steps, materials and the yarn each colour needs in a fine-wool kit and a rug-wool kit. |
calculate_yarn | Estimates the yarn for a punch needle design from its size, the share of each colour and the needle and loop height, or from a measured swatch. Returns metres, grams and whole skeins for each colour. |
resize_pattern | Rescales a library pattern, or a design of a given size, to a new width or height with the proportions kept. Returns the new dimensions, the number of printed A4 and US Letter sheets and, for a library pattern, the yarn at the new size. |
match_materials | Checks whether a punch needle, a fabric and a yarn work together, using the website's material guidance. Returns the verdict for each part, what to change and the checks to make on a swatch. |
get_material_guide | Returns the website's guide to one punch needle material: needles, needle sizes, fabric, monk's cloth, yarn, floss, hoops or glue. The guide holds its sections, tables and related pages. |

Your data
The app only reads. Nothing you ask is stored, an image you name is read once to make your pattern and is not kept, and following a link from a result to this website records no click. See the privacy page and the terms.
Troubleshooting
If the tools do not appear, check that the address above is entered exactly, with no authentication, then refresh the connector or start a new chat. To make a pattern, give the address of a public PNG, JPEG or WebP image.
