PicsToKnits is a web based project which allows a user to convert any image to a knitting pattern which forms a blanket or throw. The image is split into squares to knit.
upload any sized image
crop as required
produce a knitting pattern
You have a list of the colours used in the image which you can change, maybe to match the wool that you have handy or create a new artistic feel.
This project easily lends itself to a collaborative effort, distributing the pattern for each square amongst your group.
It is built around the ideas of simplicity, innovation and collaboration.
