I took part on an online workshop with Andy Skinner call the Book of Secrets, obviously I can't give away any of Andy's secrets but you can check out the class for your self here.
I will say that I've not been able to give this piece the time it's due as I've had the dreaded bug that's been doing the rounds. It's not perfect but I know why and where I went wrong. I'll be experimenting a little more to perfect the fabulous techniques that Andy taught us. Looking forward to the next class.
