To simplify foam unfolds, these details are often removed or segregated as it’s easier to add them in once the bulk of the foam piece is done.ģ. The final big difference between the two is due to the difference in thickness in materials. Paper is obviously extremely thin, whereas foam commonly ranges from 1mm-12mm, and even higher.
Remember that two faces come together to form an edge. Where sections of armour or props have an edge, paper patterns need to include both faces in the unfold that make up the edge.
For foam though, the thickness of the foam acts as a second face, so templates only include the larger face – up to a limit, where another piece of foam may be needed to make bigger faces.
