You can add a pattern by selecting “contributions” from the profile menu drop-down. If it is your first pattern, you will need to add the pattern entry to the database first; once you publish the pattern to the database you’ll see the option to add it to your Ravelry store. If there are other patterns by you in the database, please write us with a link to the Ravelry page for the pattern entry in the database, as well as your username and we will connect you to your patterns.
