Note that while I was colouring-in the Flossing Tool, I recalled that my friend Trent who is house painter uses a method called, “Cutting”. So, first I “cut” the edges before colouring-in the outline. https://www.thespruce.com/how-to-cut-in-interior-trim-paint-1822824
Note: I would not “tape” a drawing … Amazing how much observing others while they work pays-off, right?
