Or is anyone else a member? It's callled My Sewing Circle. Anyone who is familiar with Ravelry (the online knitting community) will be familiar with how MSC is set up.
It's pretty much a place to share and show off what you've made and what you want to make - there is a place for all of your fabric stash (and, hopefully soon, pattern stash too) and it is designed to show off your projects.
It's early days yet for it, but I find in Ravelry somewhere I can ask questions of people or look at what others have made out of a pattern or yarn - both of which are incredibly helpful for someone who is unsure of themselves or indecisive about what to make. It's also a great place to try to persuade or dissuade others from the things that you have tried.
I'm thinking of starting a Sew Retro group for anyone who wants to join up and join in. If it's still too unfinished for you, come back in a few months and I'm sure it will be better.
Just a thought for any of you lovers of social media! Now off to flood them with all my vintage pattern images..
