The cutting board I use at home is about 12" x 24". Kind of an oddball size but plenty big for my use.
Whenever I use it I wash it down 1st and again after I am done or in between vegetables and meat.
But sometimes I get a bit annoyed when I am just cutting a couple vegetables or something small.
So about a year ago I told myself I need a small light duty cutting board. After a while my wife started saying that if I didn't make one, she was going to buy one at the store.
This afternoon I had an hour to kill, so I cut, sanded and oiled a small piece that used to be part of a shelf in my work area.
Now I will take it home and see how often I use this instead of the larger board.
If you decide to make one it is a cheap and easy project.
Buy a short board, sand it to 400 grit and oil it with mineral oil. No talent required.
