All my patterns are listed on Ravelry so, if you’d like to keep track on Ravelry of which PlanetJune patterns you own, simply find the appropriate patterns and click ‘add to library’ from the pattern page (in the same way as you can add the books and magazines you own). The patterns will be listed as ‘Single Patterns’ in your library.
However, I do not sell my patterns through Ravelry as I don’t sell PDF copies of crochet patterns, I sell perpetual single-user licences for my patterns, which give you far more! All pattern licences are processed through the PlanetJune shop, and they offer you all of my licencing perks (including unlimited downloads, free updates, customer support whenever you need it, etc).
