Cutting Board of Wood with Modification
A few years back, my son and I were talking about my cutting board, and somehow the discussion turned to how nice it would be if a person could cut over the sink.
He, as teens often do, left the room for a while, and when he came back he had this cutting board cut and assembled that fit across the top of the sink, yet had legs that went inside the sink and kept the cutting board from slipping sideways.
I have been using it ever since.
It's easy to clean. I just wash it like a dish. Soapy rag, one end in sink. Scrub cut materials off. Rinse. Dry. Ready to use again.
