Flame lines

I would like to produce simple looking flame lies as shown in my image:


I drew those orange lines in paint. They’re going to be flashing in final production. I would like to know how to add them to my code. Does anyone know of a method to accomplish this? I’d prefer using a simple method, but I’ll do whatever.


Could you tell me what I need to do? I hope this image helps…
