Thanks for the tips! I'm a little fanatical about keeping my machines clean, so hopefully I'll avoid that pitfall.
I had wondered if some of the "bobbin threads" would be an issue. I got my hands on a sample of filtec bobbins a while back and really disliked them. The thread kept breaking with regular sewing. I didn't buy any more, and I have 3.5 of them here I will probably never use.
I have no computer boards in any of my machines. Apparently I'm "old school"
Thanks for the reminder about breaks. I'm terrible about remembering this. When I FMQ at our sewing circle, I get told to get up and walk and stretch. It doesn't occur to me til I hurt the next day.
