Thanks to everyone who took the time to comment on Pinterest. It looks like the general consensus is that Pinterest is a major time suck - something I definitely don't need right now. I am so behind on sewing, I can't afford to procrastinate any more! I think following someone else might be a good thing. =)
That said, I saw on PR that there's a new 2-week sewing challenge that involves Pinterest. The challenge is to sew a home-dec item inspired by something you pinned. Click here for more information.
