I just discovered, via a home construction project, that lumber crayons exist. Until last week, I used pencil when working with wood for a project. Little did I know a world of colourful lumber crayons was living in the local hardware store. Available in a wide range of colours, lumber crayons last 10 times longer than ordinary crayons and are water, fade and smear proof on wet or dry wood, metal, concrete and most other surfaces. Colourful and technically amazing? What a schmuck I was with that silly pencil. I am quite partial to the hexagon shaped and florescent lumber crayons. Maybe it is time to go to the hardware store on a colour-finding mission?
