Craft Fairs are great ways to find cool items that you might not be able to find anywhere else - you're getting to benefit from the creative power and imagination of Sacramento's finest artisans! Craft fairs are also great inspirations for your own creations. And whether or not you plan on making your own crafts, don't forget to ask the artisans how they created their work - they often love talking about their craft, and you can learn some really interesting things.
There's also a very respectable collection of crafts at Sacramento Second Saturday.
The former Sacramento Craft and Flea used to be the best place to get crafts in Sacramento.
