Getting Down With My Sewing Machine

I stopped by JoAnne's yesterday and was totally embarressed when the lady asked me what model of sewing machine I had, and I didn't know it.  I was looking for a teflon sewing foot, but in order to get the correct one, I needed to know the model number.  This weekend, I found out a lot about my sewing machine including getting a copy of my owner's manual.  I'll never be stumped by that question again.
