I am so glad you asked this! Man I LOVE that ruler!! I went a searchin' and I cant find anything like it-clear or metal. I love that all the measures are actually on there. Maybe that makes me lazy but I can use all the help I can get! But yes, white on clear is not easy. I want to trade in for the TH center ruler I have.
I was going to suggest something like that-the way TH uses it to fill in on his shifter stencils.
Do we think there is something about the Wakely paint vs the liquitex I have in the house to do that fill-in trick? Any acrylic paint should work right?
