I have at last succeeded in making the piece I had planned, though this is very much a test piece, I think I have made all the required mistakes now, so when I make another, it will be of good quality.
Speeding up the drying process by putting the cast in the oven at less than 50°C leaving the door ajar so that moisture can escape, can prevent rust stains forming (seen here in the third image).
My first customer
Sally Wakelin - Studies in Creativity 
Very nice, Sally :-) Hope the customer has tons of money (or a mouse) to offer.
No! she ran away as soon as I mentioned the price . . . I was terrified that she would knock it over and break it.
Success!!!!
Yeah – perseverence and attention to detail paid off!
