If you only visit one art store in Vallarta, make it this one. The Huichol beadwork pieces here are mostly one of a kind, there are some fine Huichol yarn art pieces, metalwork from Chiapas and ceramics from Oaxaca and Chihuahua. Pieces come with authenticity stamps and owner Kevin and his assistants are happy to discuss the art in detail.
If you want to have a go at making Huichol beadwork yourself, you can sign up for a session with one of their artisans for US$40. They also a tour on Tuesday mornings at 10am along the malecón, explaining the meaning of the symbols that pop up in Huichol art that are painted along the waterfront, while on Wednesdays at 6pm they do an art walk that takes in the small art galleries of the neighborhood. Both are free of charge, but call ahead.
