I decided to take a walk through Portobello Market at the weekend, the market is about 15 minutes walk from where I live, but I have not been there for a few years (you forget what is right on your doorstep). I found my favourite stall, its been there for years. It has wonderful vintage buttons, lots of beautiful glass and metal and just what I needed for some new (new as in projects that just needed that something to finish them, like a button and have been living in a bag for ages) projects I have been working on. The picture does not do these button justice.
I also visited a stall and got some nice trimmings, its worth a visit to the market if you are in London. There's so much to see.
