Use a tool belt. It helps you keep all the most commonly used tools and hands reach. Such tools as pencil, measuring tape, hammer, nail punch, square and a few nails or odds and sods.

Use a pair of long nosed pliers to hold a nail steady and in place until you have hammered it into the wood a little bit. This save you hitting yourself on the fingers with your hammer.

Clamp a piece of wood along the cutting line to act as a saw guide for the handsaw. Do not use your hand for a guide.
