I am confused with this question from Derek, but a reader who uses Plaster of Paris regularly might understand better:

“For scenery building I like to use plaster of Paris bandages off cuts (yes, as used with broken bones! and free of charge!). I wet the Plaster of Paris and form it into appropriate sizes/shapes to layout as suitable ‘topography’profiles. However, I can’t get such off cuts at present and wondered if – please – a reader could perhaps suggest any suitable options?”
