Colombian-born photographer Anita Calero's discerning eye is well documented in her catalog of work. Part curator, part flea market sleuth, Calero pulls off a bohemian mod look with effortless ease; her West Chelsea loft is full of inspirational ideas, such as this daybed with vintage chalkboard as headboard. For more images of Calero's abode, go to Loft Life.
Vintage chalkboards crop up on eBay and Craigslist, of course, but procuring one requires some trolling. See below for a couple of sources offering instant gratification.
Above: Marseilles Chalkboard with oak frame and measures 48 inches wide by 95 inches long and is $699 from Restoration Hardware (smaller sizes also available).
Above: School supply stores are a good place to source oversize (and well-priced) chalkboards. For a 40-inch wide twin bed, consider the 4-foot-wide, 6-foot-high Oak-Framed School Chalkboard for $206 at My White Boards (BillyBoards is another source for school chalkboards). N.B.: Sites such as Factory 20 often sell vintage chalkboards.
