Thanks guys. I suppose I need to be brave and just go for it with the real thing. There's so much pressure when you're working with such tiny amounts and it's so expensive

I'm not sure how Ireland compares to Utah in terms of humidity! I know when I took the class we were in a pottery studio on a very warm sunny day with the doors open, maybe that was extra dry conditions.
The instructor just warned us it would dry out quickly and we had to work fast, but we weren't using acrylic blocks for making snakes or even the whole washing, moisturising hands and using balm or oil thing wasn't covered, i read about that when i got home afterwards. Maybe now I know that, I might fare a little better.
Here's what I made in the class anyway, it's not great at all but i suppose it'll always be special to me for being my first piece...

And here's the lino cuts i've been working on and some test clay pieces (It's DAS clay, I think maybe that's the german kind you were talking about Kurt?)
