That's tough, Tom. Points for putting yourself out there though!
Maybe go to events where you know it's going to be a manageable size. Like your bookbinding class.
Where you have more control over the environment. Or just plan to meet with one person outside where you can wander together.
But I admire that you recognized a problem and pushed out of your comfort zone to address it. Even if it was too much, the impulse is correct.
