There is an organization in Denver that markets the Art District. I'll likely join them, and therefore be included in their marketing. Otherwise, the ___location I am working on gets a lot of traffic, and the sign in front will be the major announcement.

Our web site will also have an announcement -- it is currently just my wife's blog, but is connected to her etsy shop, so we do have a small following.

If there is interest, I can post on HN as well. I wasn't sure if the community here would have a strong interest in my project or not...

Finally, simply word of mouth - as my day job will pay the mortgage on the property, I don't actually need to profit, so I can just work with my friends on the first few shows, and get the world out gradually.

In terms of timing, I am hoping for August. Once we actually move in (hopefully on the 31st), we need to physically prepare the ___location (needs new floors, doors, drywall, lights, things like that). So there is quite a bit of work to do yet.
