I took the class yesterday. Wow! It was intense. There were only two of us in the class and we learned a lot. I had my Featherweight completely apart with this little pile of parts in a magnetic bowl. I would have freaked if Kimberly hadn't been there to guide us thru putting it back together. But I got it all back. While I will probably continue to take mine to her for problems I can't solve and for an occasional maintnenance, I do have the confidence that I can take parts of the machine apart and put it back if needed.
Momof6, have you solved your problem with yours running slowly yet? Kimberly did say that sometimes when they haven't been used for a while, they will run slowly at first and then gradually speed up.
