Hi all,
I'm using Celotex foam for my scenery. It's a dense foam used in loft insulation. I'm making rocks/cliff faces i.e, a gorge/landslip. I'm guessing it's a common material to use and I wondered what tools/techniques others had used to sculpt it. A Stanley knife blade is too short for some of the deep cuts I'd be wanting to make. I'm looking for a tool that'll leave flat, smooth surfaces so I'm guessing a serrated edge wouldn't be an option. I'd be grateful for any hints/tips etc anyone could provide.
