www.bobbincentral.com, a site from which many threads as well as machine needles and disposable loaded bobbins can be purchased. (They also have a Facebook page.)
Why would I do a post about this thread? While this thread was designed for machine embroidery, I use it for quilting. I love the range of colors (free color card with initial order if you let them know you want one). I really love the way it glides through my machine and needle. I love the size of the spools and the fact that it works so well in the bobbin too. I love the way this thread glistens on the quilt top. More than any other color, I use one of their beautiful golds that is even better than the metallics I used to use.
Furthermore, Fil-Tec/Bobbin Central has a special for February for 10% off Glide thread.
They have an extremely high level of customer service. They fill orders rapidly. (For me the only downside is the time it takes for UPS to carry it across the country--so I need to allow a week from the time I order.)
I have no financial connection with them at all (except for sending them money when I order from them).
I keep telling myself I'll take some pictures of quilts I've made over the last few decades and post about them, but time has been so crunched that I haven't managed to do that--yet. I'll get to it.
