I'm looking to use a softwood, so I can manipulate it by hand, since not only do I not have access to power tools, but said tools also scare me to death.
I was thinking basswood. If people are making blocks from foam, basswood should be ok, right? Also, how would I finish it off? Do I use some sort of finish or varnish? I'll be using plastic wrap around it, but it's still going to be exposed to a lot of moisture.
