I know - kind of weird. My customer wants his 5 baseball cookies in the bouquet varnished. Can this be done?

I'm confused .... real varnish? As in the paint dept? If so, I wouldn't use regular cookies, but salt dough.

The thing is I already made the bouquet. It was a gift to the customer from someone. But you have made a good point. I can make him another one with salt dough.
Thanks
