I've only been on their web site since Friday but it seems to be a mecca for knitters, well worth having a look and registering as they have loads of useful info. You can list all your own knitting projects, things you'd like to make etc, creating your own on-line knitting community, a sort of Facebook for knitters.
The benefit of selling my patterns on their site is you can download them directly once you have paid. Nice and easy.
I would say their site does come across as a little complicated to begin with but it has only taken me a couple of days to get to grips with it, and the Ravelry staff do seem to be very helpful (as you would expect knitters to be!). You do have to register before you can access any of the information but that can be done in a few simple steps.
Have a look here and let me know what you think. To find my patterns for sale simply search for 'Lynne Seaton' or 'My Baboo' under the designer or pattern tabs.
