connecting threads, Superior Threads and Atlanta Thread company are only 3 of many, many thread companies who have great threads at good prices and reasonable shipping policies. I think Superior is the most (informative) of the web sites with free thread/needle charts you can print off that tell you about the different threads/ what needles to use with them and their best uses...a valuable resource. i purchase alot of my thread from Connecting thread (probably 75% another 24% from Superior and 1% from the lqs or other sources)
