My sister collects orange glass. If we collected, we'd go for blue. And we might get our start affordably at West Elm, where we've spotted a few eye-catching blue glass pieces lately...

One is that glass ball lantern pictured up top. Made of hand-blown swirling blue glass, it's on sale for only $20 right now. Hang the lantern outdoors with a tealight inside for a little garden dining charm.

The Artisanal Vase Collection would get us started on a blue glass collection. It includes a large clear blue vase, an opaque blue glass pot, and a small swirled glass apothecary-style vase. The set of three is only $53 right now.
