As a result of all your wonderful tips and advice for working with the dreaded Kreinik thread, I buckled down and worked on getting some of the stitching out of the way on Sunday. It was a perfect day for stitching as the weather was cold and rainy so I had a great excuse for staying in doors. And I'm really happy with the progress I made!
I ended up going with one thread only and very short lengths. It was kind of a pain to have to rethread the needle so often but it was worth it. I was also careful to keep dropping my needle every few stitches to let the thread unwind so it didn't crimp up a lot and that really seemed to work well.
Thanks to all your great advice, I no longer dread having to work with metallic threads. Thank you everyone!
