Vintage wire decor is simple, lightweight and often cheap. This style was "trendy" around the turn of the century (19th), when practicality and function took precedent over form.
It's happenstance that those industrial accessories are now valued for their form around the turn of the newest century. The patina of the antique wire adds a dimension of beauty that compliments any interior style. Also, wire materials can be painted for a smidgen of color without overwhelming an area.
Turn of the century antiques are sought-after collectibles and can be hard to find in flea markets. Cage lights are especially popular and genuine antiques cages can be very expensive. However, if you're willing to put in the time or shell out a little extra cash you can find the lights and other wire decor in specialty shops in your area or online. Also, these accessories have become popular enough for reproduction, so they can be bought at large stores for a significantly lower price.
