It needs to be said that this place sells a ton of upholstery fabric, heavy duty outdoor or auto fabric, and lots of related notions. This is not the place to come if you're burned out on Jo-Ann or too lazy to drive there. I know because I tried. This isn't a quilting or fashion fabric shop, but it's amazing for what it is.
They have a huge selection at really great prices, but shoppers should be prepared to sort through a sea of fabric bolts and look at lots of swatches. This place is kind of amazing in terms of the quantity of material available, and it can be overwhelming! It's also super dusty, so if that bugs you, head elsewhere.
