you could paint it AFTER making it into a bowl. that way, it'll keep the design you paint and it won't get distorted.. unless of course that's what you're aiming for. I know there are sealants out there, but i'm not sure of which would be the best to use
Yeah I don't know I still just trying to think of ways. Because afterwards would be hard with painting all the curves.
I was thinking of using those painted pens but don't know if they would work. As for it getting distorted that worries me a bit.. but I guess it wouldn't matter since it would just be some random lines and such.
