start ripping stips of paper from an old magazine or newspaper
(or you can cut out pictures and text boxes neatly for a diff look)

mix together 2 parts water and 1 part flour in a big mixing bowl for the paste

completely dip a strip of the paper in the mix and apply it to the mannequin (or any other object your using) repeat this until it is completely covered

if you are using a jersey covered mannequin you must first remove all fabric and batting from the mannequinn

let dry overnight

once dry you may add extra layers

if you choose not to and can see a white residue was left behind use a damp rag and gently wipedown the mannequin (or any other object you are using)
