I did benefit from this expensive little life lesson. I have gotten much, much better about cleaning out the lint. I do it when I put in new bobbins or change thread, even though it's a bit harder on my current machine. I got a little help as to how to do that, when I took my machine in for servicing this time, so that sure ought to help. Apparently I'm supposed to lower the feed dogs when I do it. You're right, I didn't get lessons with this machine. It was used. Otherwise, I'm sure I would have learned that when I bought it.
Also I did a major debris overhaul of the table where I sew (yes, I share it with the family printer). I couldn't bear to photograph this area before I cleaned it up.
Doesn't that foot pedal, and all the machine's little bits and pieces, look sad waiting for their mother to come home?
The most important part of the cleanup was that I took all the gunk that has been piled up behind the machine, and I do mean piled up, and organized it into the wheel'y plastic unit shown below, that I found in amongst some of the stuff my daughter sent home with us, when we moved her from her last college digs into her current place. That unit is doing stellar work for me now, and I can just slide it over to the printer/sewing machine desk when I sit down for a visit with my favorite lady.
Can you believe all this goop was in one big plastic tub? No wonder I couldn't find those trouser hooks!
