I think this would be a really effective and easy technique as I can use clay to create the base shape with a lot of detail. I really want a lot of floral detail on my mask and latex is very strong and tear resistant and so is perfect as it can be stretched off of the cast at the end. whereas a different material like silicone would not be able to stretch and there for release the detail as easily.
