Hello all.
Sorry if this has been covered before. Can anyone offer me some tips for working with sytrofoam for armatures?
What's the best tool for cutting and shaping it? Do I need to wear a mask ... is it mega messy (dusty, bitty - do I need a mask and to do it in an outside space?).
I've started collected bits of styrofoam packaging from work - boxes with monitors and kit in - I'm dying to have a go!
I read a tip onthe forum about using tootpicks dipped in pva to 'nail' section together - any other beauties like that?
Thanks.

Hi Rachel,
Styrofoam (aka polystyrene) is excellent for making armatures as it so light and kind to your hands.
White (pva) glue is the right adhesive to use, as if you use an instant glue like UHU it will melt it.
You can break it up, cut it with a knife - or, if you need small specific shapes try and get hold of a hot wire (specialist craft shops usually stock these), you will be able to make very precise shapes with this tool.
You won't need to wear a mask, but you will need a hoover standing by! The small bits that break off fly all over the place and cling to everything - including you!

Hi Jackie - thanks for the advice.
Wow - I love polystyrene!! I've sculpted myself a nice little figure - now I just need to mache.
Is the best thing to add a layer or two of paper over polystyrene before you add pulp - or can you dive straight onto it with pulp?
Thanks

Or, as an alternative, you could paint PVA adhesive over the Styrofoam and sprinkle fine sawdust over it. This also would give a good key for the mash.
