The practical advice I received was to be sure to include perks at the lower tiers, say $5 and $10, to induce people to bump up from minimum $1 monthly donations. I don't know what this would look like for you--maybe posting snippets from poetry-in-progress for those reward tiers. (You can post locked updates to Patreon, including locking entries to X tiers and above.) In my case, I am lazy and only have a $10 low tier where every month I send a postcard with a doodle and a trinket to the backer, but I am abusing Joe's willingness to snail things for me plus the fact that I have an insane supply of beautiful Korean stamps/bookmarks/etc. from decluttering that I want to get rid of anyway.

Also, have someone design you a really pretty banner! I have a ridiculous kludge of a banner. I bet you could nab beautiful and appropriate art out of public domain or screencaps from movies, though; I couldn't think of any options I was going to have for space opera from public domain. *wry g*
