Thank you Jack.
For the flat pieces of wood I am working with right now the bath mat works fine for me.
When (and if) I get into shapes that do not lend them to 'flat' carving, I will definitely consider other ways to hold the work piece.
Your 'bench hooks' are what I was referring to when I talked about a piece of plywood with fences. As you noted, the problem with that is still one of having this platform slide around. When the part involves 3D shapes the bench hook, or slanted tray, sitting on the bath mat should work fine.
I might also mention that the bath mat is large enough so the carving tools are not lying on the glass desk top. The two strops in the upper left corner were made from an old leather belt. One piece was wrapped and glued around a piece of 1/8 inch plywood and is used for the small gouges.
