>>2917654I taped off ま and 荘, and the circle in り. I used pencil to draw where I wanted ひ and り, and also the petals in り. I painted the flower over the blue background, and り over the (too) orange flower. I think that's easier than trying to tape off everything. Even taping off the big circle was dumb, just draw a circle with a pencil (use a plate or something if you don't have a compass). Painting the white parts isn't really any harder than painting the text, at least when you've painted the orange parts already.
It's super messy, and the colors are wrong, but I'm not an artist. I just wanted to make them for Yuno's birthday a few years ago. I know だ still needs the numbers to be perfect, but I didn't have any spray paint, so I never bothered to do it. Actually, I'm not sure if it's even spray paint, but I would've needed some stencils anyway.
