Technically you don’t need any items for evocation. Get what you can and don’t worry about what you can’t get or make your own. I have performed a successful evocation in a hotel room in the middle of the day by closing the curtains to blacken the room and called out. It worked. Don’t get hung up on props.
When i evoke the few figures i work with i also use nothing, apart from a sigil drawn on a piece of paper as a focusing aid for Lucifer since he seems to be harder to get hold of than the others.
