The garment/fabric district is a total hoot! There's A LOT of absolute junk but, there's some treasures to be found as well. Some of the vendors are there from week to week, some are here today and gone tomorrow. A really good and complete report (including pictures) on shopping in the fabric/textile district can be found here
I like shopping in the "district" because there is SO much to select from. I take my largest cloth bags with me and fill them up as I walk from shop to shop. My husband likes to go with me because its so exciting, and he helps me carry all the treasures.
I recommend that you print off the report, take it with you, and also, make a list of what you want in the way of buttons, zippers, thread, etc. I always get so distracted by all the fabric, I forget that I also need the buttons, zippers, trims, and what not to go with it and, there are lots
of separate shops that sell those things too. I have
to take a list with me.
Shopping the "district" is akin to the kind of fun kids have at Disneyland and, its just as crowded. I LOVE IT!
