picstoknits.co.uk PicsToKnits is a website which allows a user to convert any image to a knitting pattern. The image is split into squares to knit with presets for cushions of various sizes, a cot blanket or a large throw / blanket. It even calculates how much wool of each colour will be required for the completed pattern.
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.
