We may be a crafty, DIY-forward sort of city in general, but the true motherload of all local craft events is the one and only, sometimes frighteningly huge Crafty Wonderland Super Colossal Holiday Sale. Hundreds upon hundreds of local makers pack out a large Oregon Convention Center hall, and half the city swings through to do an often hefty portion of their holiday shopping over the course of the weekend. (This year it's taking place on December 14 and 15.)
Needless to say, it is pretty damn competitive to get a booth, especially if you are already working in a saturated market (hello jewelry), but it is completely worth a try. They just started taking applications for sellers a couple days ago, and the deadline is September 15, which... is not that big of a window! Directions and friendly advice on how to proceed are right here. Godspeed, noble crafters!
