Shopping for the person that has everything? Then you won’t want to pass up this Knox Street gem. Owners Dan Dean and Mickey Miller have taken special care to fill their store with one-of-a-kind pieces of contemporary art as unique as they are beautiful. Clay, glass, metal, wood, mixed media — you’ll be hard-pressed to come up with a medium Iota doesn’t cover. Stop by for one of the in-store exhibits or simply to admire Karen Shapiro’s ceramic sculptures of everyday objects, or the jewelry creations of Chicago-based artist Kathy Frey. If online shopping is more your thing, go to Iota’s website for a peek at its e-exhibits.
