There must be a lot of places but I don't know of any.

Any Rimping Market.

Or for something completely different, the owner of the Washy Mashy dry cleaner is an amateur artist who has his own hand-painted cards for sale, mostly birds and nature scenes if I recall. It's a chance to support a local business and favor Chiang Mai's artisanal tradition.

just going out to buy one now, ksk 2nd floor,or if in town bookstore opposite mai ping hotel back entrance,not far from gecko bar.

I love supporting him and usually buy cards there, when needed. Added benefit - I'm lazy and he's just across the street! But, sadly, Washy Mashy is closed on Sundays, so no emergency card purchases today.

Is Washy Mashy the dry cleaning place on Heuy Geow? If so, I think I know where it is.
