Ok, everything I've read says vinyl stains if you so much as look at it funny. Apparently, I don't look funny enough.
I'm trying to turn some Barbie parts - specifically hands from a Bedtime Barbie - purple. It doesn't have to be a dark purple. I'd settle for lavender. I have a few scrap pieces I was using for tests. I soaked those in food coloring for hours with no result. I've tried permanent marker just to have it rub off. I don't have any RIT dye in the house, but I'd be willing to get some if I could be sure it would work... but that tutorial was for resin, not vinyl.
Should I just give up and paint the hands with acrylics like I would for a faceup and then be really careful not to rub it off? Or is there some way to get vinyl to stain when you actually want it to?
