I think that this design of mine is a really effective one.
Firstly add the white and let dry.
Add the striped red section.
Add the black sections by painting abstract 'Y' shapes. The best thing about this is that you dont have to be perfectly neat and tidy!
Add the black rhinestones creating a finishing edge where the red meets the white.
Finally finish with a clear varnish.
