A request for help on making a cast of a handprint in concrete has been buried in a tale of tragic woe. Evil realtor sold a house that OP had been foreclosed on decades ago. Seems the real world is supposed to stop so that OP can continue to live in a house filled with bad wiring and other hazards. OP had been arranging for 'Fannie Mae" which I understand is some US tax payer supported thingy to do all the renos and allow OP and family to continue living in house. EBIL people who bought the place are just ebil.
Why do we need to know all this? Just post that you want to make a cast of an impression.
