I have found some fantastic suppliers online! Here a a couple of recommendations. I hope they are of help to you.
For the most extraordinary threads ( Finca, Perfect Quilter, King Tut, etc.) and outstanding customer service, I suggest you try: http://www.sewthankful.com Tracy Chapman is the owner of this site and I cannot say enough wonderful things about her. I want to be up front and let you know- she is a personal friend of mine. And she is one of the most ethical businesswomen it has ever been my privilege to deal with. Check out Tracy's website and tell her Rachel sent you!
Another recommended site is: http://www.handyhandstatting.com Barbara Foster is the owner of this site. The variety of tatting supplies, threads, and books that she offers are amazing! I teach needle tatting using Barbara's book Learn Needle Tatting. Her book contains wonderful photos and step-by-step instructions. Mrs. Foster teaches novice tatters to learn how to read different pattern styles, as well. I have always received excellent service and prompt delivery of all materials ordered from this nice company. I hope you enjoy it!
