I started out with just a few things from Walmart: a simple white fabric shower curtain and two bottles of fabric paint in dark grey.
Then it was just a matter of using a quilting ruler and a pencil to draw the lines. If I wanted to be exact about it, I could have used painter’s tape. Instead, I free-handed it, and it has a lovely, almost street-art feel to it, with a lot of “mistakes.”
A close up of the painted lines:
Oh, and a quick before and after. I like the openness the new curtain brings, and the variation in scale as compared to the tiles.
