What to do in a thunderstorm?

I always turn my computer off when there's thunder about - paranoid maybe but I don't want my precious Mac dying on me because of a power serge! There has been plenty of rumblings this afternoon here in Leeds so whilst the skys were going a little crazy I took the time to make up some cards.
These I screen-printed a little while ago but thought they looked a bit drab so have been 'colouring them in'. Now they look like a just doodled card ready to send - perfect for my next craft sale!
