connecting threads has a wonderful supply of great threads, very reasonably priced, lots and lots of colors, weights, types...another good source is Atlanta Thread company.
i've been buying all of my thread from connecting threads for about 6 months and am so happy i found them. i used to have such a hard time with threads being horrible to work with for all kinds of reasons, tension, breakage, skipping...the list goes on..all of that ended when i found a source for quality thread :thumbup:
