The center of the city is called "Old Town" and it is the epicenter of tourism for the entire province. They mark off the already-very-unaccommodating-for-traffic streets and don't allow any cars to pass through on the weekends. It is absolutely massive and I was hopeful that it would be unique. For someone who hasn't spent much time in this country it might seem like it is unique but as a seasoned veteran of this country I can promise you that it is, in fact, not unique.
I am slightly claustrophobic so this for starters, was the wrong place for me to be. There are entirely too many people here and the rows have been set up to be far more narrow than I feel they should be. It is almost impossible to even stop and have a look at the wares someone is selling without blocking the 437 people that are walking behind you. You gotta be really quick to get your hands on some merch.
Other than the massive congestion of people the things they have for sale have spurious claims at best. Many of the sellers are claiming that their items are hand-made locally and while I don't doubt that some of it is, I really doubt that most of it can make that claim honestly.
While i am certain that these things were made by someone's hands I don't think it was someone local. I have seen some EXTREMELY similar items on offer in just about every other tourist market I have been to in Thailand. It wouldn't surprise me at all if they all came from a factory and the ability to sell these things are dictated only by the salesmanship of the person working the stall.

get me outta here!
I asked the few local Thais that I know if they ever go to these markets and they laughed and laughed and laughed and basically just responded with "the only local Thai people that go there are selling things at it."
Overall Consensus or TL;DR
If you are ever visiting Chiang Mai, i don't need to inform you of where this is. If you are in the city center (and you likely will be) you will find it because it is unavoidable.
It might sound like I am whinging and to a certain degree I am - I can be quite negative about things that annoy me. If you are simply spending a few weeks in Thailand you will likely be able to find some sort of memorabilia in this market and other ones like it. However, if you approach these things thinking that any of the stuff in it is authentic, one-of-a-kind, or not mass produced, there is a very good chance you will be dead wrong about that.
