First test with Superior Metallics. They are wonderful. No breaking, no need to try and readjust anything. I just threaded the machine, used my usual poly bobbin and it all went smooth.
The pink/blue/silver one in the bottom part is Razzle Dazzle used in the bobbin. It was my first time to do bobbin work and I am surprised how easy it went.
So now I know where I will spend a lot of money next month. ;-)
