I've been here at least once a month to get art supplies. They have pretty much anything you'd need for all sorts of art and with the highest discount, compared to Blick/Utrecht.
They also host painting classes and advertise other artists in the valley. Thas purtay coo
The only drawback is that they don't carry much of the more specific stuff for textile painting like water-based Pebeo gutta in tubes or artificial dispersant (which is really just Oxgall, which they do have) They have a ton of textile paint/silk paints/batik/regular gutta in a can/etc though - the usual stuff and then some.
The variety and deals here more than compensate. It's not like everyone here wants to get gutta in a tube haaa
