It's impossible to imagine now, given the range of designer colors one can buy, that in the early 17th Century, that artists such as Caravaggio, Rembrandt, and Velazquez didn't have an affordable or stable blue to use. Ultramarine, which is extracted from lapis lazuli, was more expensive than vermilion or even gold. Artists had to cough up a princely sum to have the blue pigment imported from Afghanistan. That's never been the case at Jerry's Artarama, the 20,000-square-foot West Miami art supply emporium featuring almost anything the fledgling or seasoned creative type might ever need to succeed. At this sprawling one-stop depot, you can find everything from acrylic and oil paints in every designer shade from the world's top brands to brushes and palette knives. You'll also find canvas, stretched or in rolls and made from cotton, linen, or jute. Plus pens and markers, encaustics, ceramic and pottery supplies, water colors and pastels, airbrushing supplies, easels, portfolios, and even a custom framing shop tucked in the back. Budding Picassos can take weekend easel painting classes conducted in English, French, or Spanish for $25 a pop, not including supplies. To top it all off, Jerry's boasts the type of cut-rate prices, sometimes ranging from 50 to 75 percent off, and savings on hard-to-find items that would inspire the likes of the old masters to turn cartwheels in their graves.
