Bits of Threads, to the NYC Garment District. Hard to believe how much is jam-packed into this 1/3 square mile. Besides Elliot Berman & Mood, the notions shops are irresistible. (I took one regular-sized backpack: when it was full, I stopped shopping & headed to the MoMA to see the Matisse cut-outs show again.) And if you get tired of fabrics (or are traveling with a Roommate who might get bored), the Empire State Building & the main branch of the New York Public Library & Bryant Park are all close by. NOTE: Bryant Park is especially fun this time of year with a Christmas shopping festival & an ice skating rink!
Here is the Garment District's official map (in PDF form), if you're headed there yourself.
Right next to Elliot Berman, at 237 W 35th St, I found Butterfly Fabrics, and they had an amazing selection of West African wax prints, along with wonderful embroidered Indian silk, sari fabrics, and raw silk (reminded me a lot of being in a fabric store in Abu Dhabi). I *only* bought 27 yards of the wax prints, and the only reason I didn't buy more was because I couldn't figure out how to carry it!
Speaking of wax prints, Yinka Shonibare has an interesting take on these fabrics and their meaning. He's a Nigerian-English artist, who uses West African wax prints to show the legacy of colonialism. (Here's the page about him on Wikipedia.) I can't ever resist wax prints (as you've noticed), and love his use of them in his artistic commentaries!
