The one draw back to having a custom work of art doll, is that you really can't change it afterwards. This can be incredibly frustrating if a mistake is made. I am forever in search of a method so that changes can be made afterwards. Sometimes I think it's good to share our blunders and utter failure as well if not to help others avoid the same misteps.
The first time I attempted an eye change after the fact, I used the boiling water method of changing eyes. I tried very carefully wrapping the face and making sure I didn't spill any boiling water on the face, but when I came back to the head after 10 minutes and the vinyl was soft, so was that face-up. In fact it had melted off, I was missing eyebrows and it looked like runny mascara. I am pretty sure despite my best efforts that I did end up getting some of that boiling water on it, and it melted that face up right off. A definite no-go in fixing the issue and in fact making it 10x worse.
After some time I had a head that I put eyes in that somehow looked cross-eyed and I didn't know how I missed it before the face-up was done. Was put in my oopsies pile for a while and it was a shame because the faceup was beautiful. Thought I would try to be clever and use the blow dryer method to either get the eyes out or adjust them. Bad news was the head opening on this was unusually small and I couldn't get my fingers up inside the head to properly push the eyes out, so the next best thing was to adjust them while the vinyl was soft and make them not look cross eyed. The good news was that I accomplished that. The bad news was that the sealant "Mr. Super Clear" on the faceup transformed into a fine white speckle across the bridge of the nose. While it was not visible in certain lights it showed up quite clearly as I turned the head and was not "perfect". At this point we can confirm that the sealer is compromised anyhow, I did remove it with nail polish remover which basically stripped it off and then the nose can be re-shaded in that area and re-sprayed with sealer so all is not lost.
