I asked David to make me a garden dibble out of wood. He gladly created one for me in less than an hour out ot Silver Maple. A garden dibble is a hand tool used to make precise-depth holes for planting seed. The tool is notched and the first line denotes 1/2 inch. The subsequent lines are in 1 inch increments.
Here I used this tool to plant snap pole beans. It's very convenient to be married to a wood worker.
