For vintage, multi-colored-and-striped heirloom rugs, look no further than Brooklyn-based Morris Etc. They've accumulated a collection of wonderful hand-loomed Aguayos, each one of which is completely unique.
The sizes for most of the rugs are approximately 57"x 63" (some larger, some smaller) and prices range from $375 to $420. There is also a collection of runners on the way, and custom designs available.
Since these are advertised as vintage rugs, it'd be nice to get a little more background information on where the rugs are made, how old they are, the condition they're in, etc. We found that all a little lacking on their site. But the rugs are beautiful, so we'll definitely keep an eye on this business.
