Hi all, I'm currently working on my latest project and will soon be at the stage where I'll be planning on making a mould. The sculpt is a mask shaped like a deep bowl with details on the inside and outside. I'm trying to think of the best way to make a closed mould for it so I can capture details on both sides, but the shape is stumping me slightly... Any ideas? I was thinking about making a two-part mould using Rebound 25 and perhaps strengthening the outsides of the mould with some pourable silicone, but wanted to pick your brains to see if anyone had any better ideas! Like I say, it's a bowl-shaped mask, circular around the edge and is about 4-5" deep.
