I've done that before with my featherweight. I wrote a note and put on the machine last time I used it so I would remember. I don't use it very often so it is easy to forget.

I LOVE your blue featherweight, God I wish I could afford a purple one <sigh>

I'm sorry but I was laughing when I read your problem. Maybe it was the way you presented it but I am still laughing, not at you but at the problem.

Oh, I might make the same mistake twice. Particularly after I sleep a couple of times.lol.

You have arrived as a member of the dummies' club. We all have done dumb things with our machines. My Bernina 1090 would not sew. I checked everything, even took off the back to see if thread or something was keeping it from sewing. After three days of frustration, I then noticed that the lever that goes to hold the thread when filling the bobbin was pushed over. Need I say, I had mud on my face!!!

I used to have a little poster (can't find it after many years, but wish I could) with a cute picture of a sheepish-looking puppy with the caption, "I never make the same mistake twice... generally, it's three times or more." sigh...

Hey, I put the bobbin in the wrong way for over 20 years before I realized that the reason it sometimes slipped out of the groove was because it was supposed to go in counter clockwise, not clockwise, like the DIAGRAM on the bobbin lid illustrates.

So, welcome me to the DUH club!!

I have done this several times!

Yes, I found that out too! And to make matters even more confusing, the 99k is threaded left to right.
So, the Featherweight right to left, the 99k left to right and the Janome front to back lol, :mrgreen:

I always put those moments down to "well, I guess it was my turn to do something silly". Keeps me from getting upset so often. When you live in "Gooberville", like I do, those things happen a lot!
