If you've created a pattern that you'd like to upload to the site, click the Donate Patterns link in the left-hand navigation bar. An upload form (see below) will appear. You do not need to be a member of the site to upload a pattern. The only information you are required to upload is your name, the name of the pattern, and the pattern. Only submit patterns in gif, jpeg, bmp, or png format. Also, take note of the maximum height and column limit. At the time of this writing, the pattern you upload must be less than 20 rows tall and less than 42 columns wide. However, this may have changed by now so read the note above the upload form. Not all patterns are accepted onto the site.
