Plaster of Paris can be used for both home improvement and decorative needs. Though plaster cannot be sculpted, it can readily take on the forms in preset moulds fairly quickly and easily. The moulds can be used to create art projects or decorative moulding used as trimmings on walls, ceilings or columns to create a more Victorian or opulent decor for the household.

Pick a mould. Pick out a mould for the plaster to be cast in. Molds can be found at arts and crafts stores and some hardware stores. The moulds at hardware stores are moulds and trims for ceilings, walls and columns.
Mix the plaster. Follow the manufacturer's directions on the back of the box or bag to mix the compound. Mix in a plaster container for easy cleanup. The general ratio for mixing is one part plaster to two parts water. Mix it with metal whisk.
Spray the mould with cooking spray. This will make the release of the dry plaster easier.
Pour the plaster. Slowly pour the plaster mix into the mould, filling it evenly. Once filled, lift the mould and tap the surface to avoid air bubbles. Level off the plaster using a squeegee or any flat edge, such as cardboard.
Let it dry. Let the mould dry for 30 to 45 minutes. If planning to hang the moulding, insert a U-shaped wiring into the back of the mould while it is still wet.
Release the mould. Turn the mould over and gently push the plaster mould out. When released, smooth out edges with a knife or finger nails. The mould will harden completely within 24 hours.
