Good practicing. I picked up on your statement that your machine is skipping.(Bottom right leaf?) Music to my ears. Mine does too, and I try to diagnose when and why. It "sounds" to me like the needle is not going all the way down and engaging the bobbin thread. I have tried numerous combinations, mixed the threads up, tension, changing the needle, speed, yada yada. No one seems to give a good solid fix. What is your take on why it skips? I have a 2 year old Babylock Symphony, routinely serviced, and the dealer doesn't have an answer.
