Miriam, thanks. That's good to know. I may need to also look at the bobbin carrier. The thicker threads didn't stay in the "guide" which, as you mention, could be the bobbin tension. My first thought was the thread was too thick for the carrier guide. I'll do some experimenting. I do love using the 201 not only for the larger harp. It just seems to fit my mechanical preferences. It is just so "perfect."
