Good old slip and score. I do like to make my slip with vinegar, rather than water, as it seems to give me a better grip, with less swelling of the clay. If that makes sense.
Great video! Here's my comment...Beware of this thing called Intellectual Copyright Infringement. Look it up. It basically says that if you didn't create it, don't copy it! If you copy someone else's work, then sell it, it can financially ruin you. Be careful what you copy. I'm sharing this with you because it happened to me. Working with clay is fun and you can do so much with it but there are legal ramifications if caught selling copies of someone else's work. I did it not knowing that I was doing something wrong. It's not worth taking the chance. Create and be happy!
Preserving your grandma’s pin is great, but some person designed it, and making copies of someone else’s artwork isn’t cool, or legal. I’d say keep the copies for family, and don’t sell them. I believe you can change the design at least 10 percent, and then it’s legal. I personally think you should change it more. So use the pin as a starting point, and make enough changes to make it your own. Not to rain on your parade or anything. I’m amazed at the number of people on YT who make castings of others’ work, and sell them. Industrial or generic stuff, no problem, but not art or designs.
I know this is old, but why not just hot glue the cicada to a slab, place pins discretely and cut the tops, and pour plaster over it? I think we are over thinking it. I know y’all got plenty of cicadas to try… so go for it, experimenting is NOT a waste of time…. It’s just as important as making finished work
