As Prism99 pointed out - try pico textiles. I like picotextiles. I have never bought a roll, but I would go to them to check it out
marshall dry goods wholesale has fleece. I have bought from them before and if they have what you like they would be worth talking to as well. They are wholesale but as long as you have a business name to ship to they were ok with shipping to me
