Erush,
Just be advised that you probably will have to do some touch up at the end. The wrapping-grade tissue may not hold the paint when flexed, and it could flake off a bit.
Another thing I thought of was to draw the circle and the Iwastika as above, but then glue it down and let dry before painting. That way you only have to paint the areas which are exposed. I dunno which way I'd try this myself, though. As I said, i haven't actually done one of these yet, this is all theory!
Anyhoo, try it on something "scrap" first and see how it works. Good luck!
