Sitting on a dorsal fin??

Hey guys!
I have a question about having a dorsal fin. I want to order a silicone tail from Mertailor in a few weeks and i want a dorsal fin so badly. But now i am worried about it because i am also a mermaid artist on birthday parties. Also for children. And i am going to sit most of the time. Now i am worried that the dorsal fin could get damaged by sitting. What are your expiriences?

Greetings from a German mermaid!

You could have it made so that the dorsal fin sits lower down on the tail instead of where your bum is.

That's a good idea! I hope it's possible. It's my first silicone tail and I don't know what the possibilities with Mertailor are.
