Yup- I use Sculpey to make the original, but I don't bake the pony with the clay on it... I've got a system where I remove the piece I'm making before baking. The issue being that the clay likes to stick to the pony, not because I'm concerned about baking the pony...
I have tried putting the pony in the oven and they do not melt or mess up in any way. you can only bake it 3 times, I learned that the hard way... anyways the degrees is 270. just a tip if its too hard to take the mane off the toy
For the colors on your models, do you do it by eye, or perhaps using those monitor calibration "colorimeter" gadgets or do you actually do it by using some sort of reference codes and translation tables/formulas to convert between screen and paint/dye colors?
And how much different are the colors in person compared to the photos you got here?
I do everything by eye- which is odd because I'm red-green color deficient. No fancy matching or anything- just do my best to match- and sometimes the first one or two of them look a bit off (my first Trixie looks too green because the blue I got didn't lighten up how I thought it would...)
It's hard to say about the colors- I try to use photos that I feel represent what I'm seeing, but it's not always possible if the weather is bad and I can't get any natural light in the shot.
