Going to a junk journal hobby event

I 23f went into a local art store. they told me there having a junk journal hobby event this week that I should come to. It sounds like just a bunch of people hanging out and talking and trading craft stuff. My boyfriend encourages me to go since I want to get into craft stuff.

I am just so scared and shy to go because I never been to any event on my own.

Any tips for going to an event all by yourself for the first time? Or maybe what things I should expect? Or what should I do? Etc I don’t know😅
