I made some signs for my pool area a while ago, but I wasn't happy with them, I had painted the signs on some old fence palings that B2 cut and drilled holes in for me.
But I didn't think the white on the grey stood out enough so here is MARK II
I sanded the old letters off and painted the signs white and when the white was dry I sanded it a bit to make it look old.
Then I just handpainted the words and when they were dry I sanded again.
Here they are hung on the pool fence with some old twine I found in the shed.
