I am another Pinterest lover. And yes, janer I do have to guard against 'always planning and never doing'. I think I've managed to sort that one now! I don't have loads of boards or loads of pins, mostly crafts, and I do try to pin only things that I am reasonably confident I would like to make one day. And I try to keep it up to date by removing pins that have become irrelevant (things for newborns for example, now that my latest GC is past this stage). I couldn't stand having thousands upon thousands of things pinned - how on earth would I ever find time to look through them all, never mind actually make them!
On the 'notifications' tab I frequently read of people I follow who have, e.g., 'saved 354 pins'. What? 354???? How long do you plan on living?
I use it as a resource, just as I do with Ravelry, when I want ideas for something I'm planning to make. And I do love meandering through it when I sit down for a cuppa
