White Polyethelene Blocks

I have purchased it from these folks. It is not cheap, but not all that unreasonable, either.

The Cutting Board Factory

The Cutting Board Factory not only has neat cutting boards, but they are also a source for large sheets of material from 1/8" up to 1 1/4". Some of it also comes in different colors. I use different colors to make jig bases and then use the white to make the actual "shaped" jig so I can replace it if I mess it up. I have also found that it is good to use as guides for my table saw. The wood slides easily across it or when butted up against it.
