A few of my favorite suppliers are listed here. Some suppliers offer fabrics, others offer trim and drapery hardware for your additional décor considerations. You can't go wrong with any of these beautiful and high performance materials!
Please note: This is not a complete list as I also have accounts for many wallpaper, carpet and furniture suppliers as well. Feel free to ask for additional design assistance. I may be able to direct you to a designer or assist you myself.
