INTRUCTIONS:

Notes:
1. I would recommend having at least two people do the casting and moulding.
2. The model can get uncomfortable staying in one position make sure they are fed and watered before and have had a bathroom break.
3. Make the model aware of the timeframe of the process. Make sure she knows that if she wants to stop at any point how to do so and that it’s ok.

Duration:
• Prep time: 1 hour
• Alginate casting 5-10 minutes
• Plaster bandages application 15 minutes
• Plaster drying 15 minutes
• Clean up 5 minutes
• Plaster mix then pour 25 minutes
• Setting 24 hours
• Demoulding 20 minutes
• Clean up 30 minutes

Overall: 27 hours:
(2 hours 10 minutes moulding and casting, 24 hours set, 50 minutes demould and clean up.)

What you need:
• Vaseline
• 2x 900g of alginate
• Water
• Plaster bandages (pre-cut into strips)
• Cotton wool
• 2x buckets
• Plastic sheets
• Measuring beaker
• Bobby pins
• Scissors
• Towels
• Scalpel / dremmel
• Tweezers
• Large cushion
• Soft brush
• Carving knife

Method
1. Prep area and materials before you start, as whole process needs to happen in one go.
2. Pose model and Vaseline her.
3. Mix alginate 1:3 ratio of water (this can be mixed with a drill whisk). You have 5 minutes curing time to work with.
4. Cover model when alginate turns pale pink: work top to bottom. Keep scoping alginate up until it turns white and sets. *Cotton wool dab: do this before the alginate sets. This will help grip the alginate to the plaster bandages.
5. Dip plaster bandages into water, squeeze water out. Work top to bottom. Add thicker strips around the edges for strength. Let it set for 15 minutes and until its dry (you should be able to tap it and hear a sound).
6. Take the mould off of the model; get her to take a deep breath and wiggle.
7. Place mould onto a large pillow for support.
8. Cut away excess alginate from the mould and using the bobby pins grip it to the edges.
9. Vaseline the edges of the plaster bandages and alginate so the plaster cast wont stick to it.
10. Mix the plaster, lots of it. Start by flicking into the nooks and crannies and then as the plaster thicken push up the sides of the mould.
11. Add a wooden tick for strength and support.
12. Allow 24 hours to set.
13. Flip cast onto it back so the bandages are facing up.
14. Using a scalpel or dremmel or hands remove the plaster bandages.
15. Carefully remove the alginate, rip it off in bits. You can use tweezers to pick the smaller pieces out.
16. Cleaning mould: while plaster is still damp (it will feel cold to the touch), make a thin plaster slip and smooth with hands or with a soft brush over any air bubbles and cracks.
17. Using a carving knife cut away excess plaster, or week edges, and smooth it off.
18. Give cast time to fully dry, it will be need to be somewhere warm where the water can evaporate. The casts weight will decrease as it dries.

How much material do you use for that belly casting?

Nice movie. However you should take instructions from woodprix website if you want to learn how to make it easily.

Hiya, how many meters of bandage do you think is required? I've got rolls that are 8cm x 3m.
