It's hard not to be a fan of Blick- they have nearly every conceivable art supply, from preschool paint kits (left wall) to professional-quality easels and design desks (back wall), and almost everything in between. The sheer number of oil paint, acrylic paint, and watercolor options is almost overwhelming.
Favorite items here are Modpodge (available for a price comparable to what I've found online) and various gift items (journals, make your own doll kits, various books). I would love to see them add to their scrapbooking section, but other than that, the only item I had difficulty locating was glitter.
Service was cheerful and upbeat, but the store is organized in such a way that you don't typically need assistance. Bonus points for the community art project outside during Grand Opening week!
