Thank you for your input. I am not to the point of having anything but pop-ups with bases as molds, so in terms of overhangs there should be no problem.
I am not a high-production glass person, so it would be at least a half hour between uses of each mold, so I think I'm okay on temperature. Can't wait to try! I just haven't decided which design to start with.
I've been asking everyone this question: Which 3D sculpting software do you use? I am having trouble wrapping my head around any I've tried. I'm a Photoshop person!
I want to make realistic statues/figurines, primarily dogs, cats, horses; something you'd see at Royal Doulton. I have a storefront at www.cafepress.com/gangwaygraphics, which is fun, but I have wanted to do 3D for a while.
I thought this way might be easier than actual clay, wood, etc., but not so far! I'm not much of a geek.
Thanks again for your time.
