taking casts of my body and the hot water bottle with alginate then plaster

I wanted to capture folds of skin, places where I might hold a hot water bottle or clutch something for warmth/comfort. The detail on the skin is incredible, although I’m not sure how obvious eg the underarm/stomach casts are.

Could I intersect these with hot water bottle casts? Show them clasped together? could I combine them – blurring objects with human bodily features?
