To be honest, if you are volunteering, it will be 3 full hours (9am-12pm) and then about 20 minutes to choose fabric afterwards. If you are motivated by the offer of the free 5 pounds of fabric, know that the pickings are real slim. It's mostly leftover and end of roll scraps set aside in the cubicle shelves to choose from. There used to be some decent rolls to choose from, mostly upholstery fabric that included some lightweight stuff that could be converted to dress fabric, despite that they were sending all the good stuff to the Manhattan store.
But once they closed the Manhattan store, none of those upholstery-like fabric rolls are even included in the "volunteer's 5 pound for free" pick. If you want anything decent, they say you'll have to pay for it. And even then, the choices of those "exclusive" rolls aren't that great. And the prices aren't much of a bargain and can be gotten at a jobber in the garment district, Fulton street or Jackson Heights for the same price range or less.
Who knows where all that rumored designer fabrics go, or even the nicer fabrics that could be gotten in the Manhattan store, because I have never seen them. They guilt you into paying and donating to the cause, and will always ask if you want to donate your "change" when you are buying fabric. Sure, you can make something from scraps of nothing if you are creative, but there are no real bargains here.
Most of the recycling volunteer work is separating fabric scraps from paper and cardboard that is used in wholesale company to display the samples. There is a tremendous amount of scrap paper that gets recycled. More than actual fabric. The proprietary stuff (a/k/a designer fabric swatches) are separated elsewhere by paid employees. Volunteers never see designer stuff. read more
