Camo or rolled up cargo netting for vehicles also. Its also known as cheesecloth. You can find it in the DIY stores like Lowes or Home Depot in the painting supplies section.
Drop it in wet plaster and you can use to help support forms over ground work or for RR layouts as well.
For helmet netting I use toule found in the bridal section (basicly veil material).
