I use Gutterman Mara 100 for piecing. I buy the thread at Wawak.com when they run it on sale for
1.99 each. I tried it for FMQ but it causes the same problems I have with the Aurifil. It jumps out of the
bobbin case. I need to pick up some of the washers that they sell for the bobbin threads to see if that
helps. It only works if I am FMQ very slowly. Right now I am using the Mettler silk finish cotton for the
FMQ but that stuff is expensive.
