I used RKT to make a "mitt", after that dried a bit I used modeling chocolate to add the fingertips and cover the RKT. The modeling chocolate was a great medium for this because it was easy to sculpt.

Good luck!

Your cake is amazing!!! I hope my hand looks HALF as good as yours!!! Thank you sooo much for your tips, I'll probably be using a combination of RKT and candy clay. I hope that won't make a difference, I've worked with it before and it's super cheap not to mention easy to make!!
