I signed up to participate as a vendor

Has anyone ever participated in a "fair"............

in the metaphysical fair next month, and I'm wondering what I should charge for a "memorial" scrapbook page layout.

I have a beautiful sunset photo that I plan to use as the background with some inspirational text. Also a place for a photo to be 'pasted' by the customer.

But I have no idea what to charge. It would be printed on acid free photo paper that costs about $1.29 at Kinkos.

any suggestions on a fair asking price?

thanks!
