figured out how to repaint the inside of the rainbow high eye chips.
here's how I did it since there's no real how to anywhere, and I'll make an in depth tutorial next time I do it
1. take the eyes out of the head (there's plenty of tutorials on how to do this
2. pry the colored part away from the black part. I did this by putting an exacto knife thru part of the seam on one side and an awl in the seam on the other side
3. soak the eye chips in white vinegar for at least 24 hours
4. FOR THE SCLERA (white part of the eyes). skip this if you're leaving it white. I used a combination of needle nose pliers, xacto knife, and the same awl to scrape away as much of the paint as I could. I used the awl especially for the part just around her iris since it had the smallest point. this part could use some perfection since u can see there's still a little bit of white around her iris. for this character it works, but for others I'll need to figure something out. maybe a sewing needle or pin?
5. FOR THE IRIS use an exacto knife to peel as much of the paper sticker away from the iris. there will be only left on the iris and unfortunately the only way I've been able to get it off is through just sanding it off. there's a little dip where the pupil is and for that I scraped it with the xacto knife and the awl again since the sandpaper couldn't get in such a tiny space
6. this part is maybe optional, you can put a layer of gloss all over the inside of the chip to provide a smoother surface for painting. I only put gloss over the iris. If you're doing glitter, put gloss over wherever you want the glitter to be and carefully sprinkle it over the gloss. wait for it to dry and brush away extra glitter with a paintbrush. now you're ready to paint! do it in layers, I recommend putting any highlights or shine down first, then the pupil, then small iris details, and then your main color.
7. wait for everything to dry and pop the eyes back in! this part is tricky again, but I found this video helped me, and I used the thicker end of a chopstick instead in place of the tool she had.
feel free to ask questions and I'll answer as best I can.
