hahaha I dont work uninterrupted.
It takes me 3-4days to get the face part where Im satisfied and bonding with it ,but I can get it nice in an hr even less. Id say I typically do sessions. of a couple hrs then quit and come back.
maybe 5 to 8 hrs a day.
Say 32 hrs for just sculpt. I could be wrong about time. I totally become unaware of its passage. Then theres sanding,patching any flaws in the clay after cure. Paint. I often paint and sand again then paint again. hair then for do hickys for decoration and or a base.
I spent typicaly 2 weeks to a month but, there are days I just dont work or I order a supply and wait for it. I also have side projects Im always doin a touch to while somethings in the over etc
