it's a foot stompin' event really... Maybe I'll just bring a spade and a suitable groundsheet, make everything there. If we can't find sand, we're doing something wrong. There's plenty of water, it's just the clay we need. It would be a bonus if anyone had any spare heat bricks going!
I've inboxed Tony. I'd probably like to do it same day as the basket weaving as the wife will be at that.
