Hi, would you ever join a collage event in a tea house if you were in my city?

Hi, I work in a tea house, we do every kind of tea, cold & hot beverages, some alcohol, ice cream, cakes and yogurt bowls..
Its not going so well this year (the place is a bit hidden in my small city).
I want to do a collage event, maybe on a saturday afternoon. You pay something and the event is for a closed number of people (max 30ish), and you can have a beverage and a pastry. I’ll but all the materials and put them on some tables like a self service —> you take a piece of paper of the color/shape you want (quite small like A5 so you have time to finish it and you can use it as a gift, as a bookmark, as a birthday card, anything), then you choose some other pieces of colored paper, your pen if you want to draw on it for details, your pencils (I was thinking of colored pencils kit if I can find them with a bit of quality for a good price), your portion of glue and scissors.
Also, what amount would you be willing to spend, considering that everything -from the baked goods and drinks to the materials- will be high-quality, and the event will be carefully planned by me + good music?
I just need to know if I’m the only one who would enjoy something like this in a boring city like mine + I would make sure to promote the thing with a beautiful poster.

- sorry if I made any mistake writing this, also I hope this is the right sub
