I purchased a cheap mannequin hoping to cut and make changes to the posture for the beginnings of the body. Anyone here have any ideas how i should extend the limbs? I plan on cutting the legs and waist to get a pose that looks like its poised for action, and to make the limbs a bit longer as this is only 5.5 ft and want it close to 7 ft. I'm thinking I could try making internal sleeves made from polystyrene to bridge the gap to make them longer. Any thoughts would be very helpful. Thanks community .
