I definitely understand how you feel! I’m an artist, writer, Arts Administrator, and mask-maker. For awhile, I ran three Patreon accounts, one for my art, one for artisan crafts, and one for my art marketing advice/reviews/stock resources.
The upside was that I was able to customize my Rewards and fine tune them very well for my unique target audiences. The downside was that it just took so much time! My eventual solution was to combine my artisan and art accounts into one place and keep my art marketing account going.
The way my art account works now is that I run thematic ‘projects’ on it. For example, right now I’m doing a series of Art Nouveau paintings and masks based around the theme of birthstones and birth flowers. I stick to this series theme with any creations and Rewards I do so that there’s some uniformity (since I do also have different art styles, from Art Nouveau to anime).
Now, when this series is complete, I’ll ‘re-skin’ my art account and re-tool all the Reward tiers to match my new theme. My current Patrons will also have a chance to vote in a poll on what they’d like to see me do next, which helps them feel engaged as well.
That’s how I’ve been handling my multipassionate projects, anyways. There’s no perfect solution, other than Patreon adding the ability to have one main user being able to manage various projects, which I hope will come sometime in this site’s future!
Good luck however way you go. You’ll figure out what works for you through doing!
