As for evoking it self, I recommend you find any spirit you feel connected with and try evoking them dose not matter if there is a sigil or not you can always make one for that what you can do is this find any spirit anything at all maybe it there story you like, maybe it the way they look, maybe there a feeling, these are some small things to look to when you want to work with a spirit , for making your own sigil it’s easy all you need to do is simple say there name out loud or in your mind say as many time as you like don’t put a limit and if you simple with your finger draw what you are pull too maybe a line goes some way feel it if you can draw on a paper and there you go the most important is trusting your self more then anything
