Last holiday season, Tracy Weil of the River North Arts District gave the idea of opening a shop selling artist-made merchandise a hard trial by filling a vacant spot at the Source on Brighton Boulevard. Chock-full of unusual art wares designed and created by RiNo artists and makers, the temporary store made a good impression with handmade holiday cards, artist prints, clothing, jewelry and a wealth of items produced by neighborhood residents. RiNo's had its share of struggles and growing pains, spawning arguments about whether the district still serves the artists who put it on the map as a destination, but RiNo Made attempts to prove those arguments wrong. And it's sticking: A permanent RiNo Made store is now open in the new multi-purpose Zeppelin Station development at 35th and Wazee streets, within walking distance of the Blake Street light-rail station.
