I am scared of dye. Yes I am. *hangs head in shame*
Acrylic paint will not stick, and neither will spray paint. Before I tried those, I had a go at shoe polish, but it only made them grey.
What I may do in the next study break is to strip the paint off, remove as much of the original white as possible (go go wire brush!), and give it half a dozen coats of polish. If that doesn't work...well, I may just scream.
If anyone has any other ideas, they would be most welcome.
oh no! dont be afraid. you could soak em in tea or beet juice you could even grass stain em!
