Well, after my first try, I decided to try again. This time, I was able to create crowns. Another step forward! Maybe someday I will make it to the pros :).
I found it was easier to make crowns with a dish with shallow water in it ↓
My setup. For those who are wondering, the big tripod is newly mine; it is a Bogen #3068, it was very generously given to me from a very kind pastor!
