First attempt at plaster hands using the candle was technique was not so good. Maggie's hand relaxed. For the later attempts, I placed sticks between her fingers, which seemed to work better. The end of her pinky and most of her thumb on her right hand did not develope, but I used the fingers from my very first attempt to make up the loss.
Also, a number of fingers snapped off in the process of demolding. It was an interesting process of removing the wax this time. Because the wax hardened in the water between tips, it developed discreet layers. I also stuck the mold in the freezer before pouring the plaster.
The brush on super-glue (of all things) seems to be the best thing to adhere damp plaster to itself. White glue just got absorbed into the plaster.
