Mark out your wood using pencil and ruler then place painters tape in places you don’t want the paint to show.
Spray paint over painters tape, wait to dry.
carefully remove tape.
Strain the steel wool from vinegar and Using big brush wash liquid over ruler. It can dry looking a bit grey depending on the wood and vinegar you use which is where the burnt umber paint comes to play. While you are applying the vinegar solution to wood use tiny bits of burnt umber paint and brush into wood with big sweeping strokes. Keep applying wash and paint until you get the weathered wood look you are happy with.
Create your numbers and any lettering/words on your computer and print on plan paper. This can take a couple of attempts as you get the right fonts and size.
Cut the numbers and words into small pieces and match with same size cut carbon paper. Place carbon paper carefully where you want numbers and words to go and place printed numbers and words on top. Trace carefully so a mark is left on the ruler.
Carefully paint over the traced out numbers and words.
