Fabric Depot customer service is terrific. I've worked with a few of the folks there and they are always friendly and willing to help. They also send free swatches!
In speaking with a gal there just a few weeks ago, I learned that Fabric Depot is a small business and not at all what I pictured from their name. When you call and ask a question about a fabric, they put the phone down, run over to the bolt you are inquiring about and run back to the phone in less than a minute. :)
