There will likely not be a part 2 to this. I've changed my methods a bit to allow people to still have access to the inside of the head. I didn't really think it would be too hard for people to figure out the rest of this themselves but here's a little rundown of what follows:
1: Paint the face, obviously, add eyelashes if you choose to do so. There are plenty of face up tutorials around the internet if you need help with this part.
2: Use the sticky tack to hold the eyes in place. I generally make a little worm and wrap it around the outside of the eye. It helps to use the end of a paint brush or something to press the sticky tack into the vinyl better.
3: Use the glue to...glue the top of the head back on? Run the e-6000 just around the inside of your hole and set the cap back into place. Let it dry for a good 24 hours before you go squishing on the head. If you want you can coat the top of the head with E-6000 for extra hold, and that also makes a silicone base for wigs to grip.
THE EYE SIZE IS 8MM to 10MM! I normally use 10mm but if you carve your eyes a little smaller you will need to use an 8. Any questions about eye size WILL NOT GET ANSWERED. Also, I generally buy glass/acrylic eyes from ebay or make them myself.
As promised, here's a little walkthrough/tutorialish thing of how I put the inset eyes into my Monster High customs. This doesn't just apply to Monster High dolls. You can do it with pretty much any doll with a soft vinyl head. My victim here is a skull shores Abbey.
I'll try to have the other half up in another day or two.
has compiled a tumblr full of amazing doll tutorials. There are some other eye opening tutorials there as well. If you haven't seen it, you should check it out and give her major props for doing this: [link]
