Working with foam

[e-paw]

I am new to using foam on a layout and have learned a few things along the way. First the tools you need are pretty simple. About the only special tool you need is a Surform tool , but even then a heavy rasp may work just as well.    
I am using 1 inch foam for my layout it can be cut by scoring and snapping like styrene.        
It can also be cut with a hot knife, but that makes a lot of very stinky smoke that probably is not to good for you. "I try to avoid it."
