HI, just thought I'd let you know, I found a piece of jigsaw on Kournicova, Brno, about 2 hours ago. Possibly a piece of sky, maybe sea - definitely something blue. It was only after I had walked a few hundred yards that I realised how annoying losing one piece might be, unfortunately by this point I couldnt go back as I was late for work. It's outside the back entrance to Meinl though. If it's yours, hope it'll still be there for you.
