Hi Astrid, there are several websites that list local (and national) craft fairs, shows and bazaars. Unfortunately most of ones I've found charge to join, but sometimes you can see the name of the show and the date, then you can google it to find the actual organizer or promoter. Many smaller, local shows are usually locally advertised on Craigslist or other media like this forum on Etsy. Also there are a few organizations that host their own shows, like the Western Washington Gun Collectors. There are also (I know I'm rambling on and not giving too much information, so please bear with me) several flea market type venues that are open every weekend and usually have space available. There is one in Monroe and one in Bellingham that I personally know of. I'll get specific websites and post them here for you.
Good Luck and great success in the New Year!
