Sulky PolyLite Thread
I love this thread, but after fighting for two days to make it work in my bobbin in order to quilt my design in a shining gold I gave up. Put a 50 wt in the bobbin and now all is well with the world. I'm sure most of you already know this, but just in case...
A side note, of all the 50 weight cotton threads I have I must say that the thread I've purchased at Connecting Threads is my favorite. The colors are beautiful and the price is very good. I don't know how they do it, but their fabric and threads are first class.
