I went to expensive school to figure out computer 3D modeling to make my inflatable sculpture. What a fool I was! I don't need computers or school! All I needed is a handful of mud, masking tape and a blade. The following pictures were taken while I was doing a residency in Haiti for the Nov 1st celebrations (a little bit like Day of the Dead in Mexico).
Step 1: make or find a form you would like to copy
I made my form from some clay dug out of a drive way. I used a a piece of wood to shape and simplify my form into planes, you dont have to do this but it makes for a simpler pattern. You could also copy a pre-existing object, say a detergent bottle or a fruit, but first ask your self if you could not simply peel the fruit and use the peel as your pattern.
