Who should be teaching and what?

Last night our monthly Mavericks Art Quilt meeting was a travesty. Because our regular meeting site was unavailable, we held our meeting at the Bernina Connection. Since we were sort of barging in on their regularly scheduled Wed. night creative club, we were forced to listen to their scheduled speaker,who I shall leave unnamed. What a nightmare. This lady, who I'm sure is quite a nice person, showed up with enough quilts and notes to speak for probably days on end, but sadly, had very little to say.
For starters, although she said she had been sewing for 30 years (who hasn't?), she had only been making quilts for three years. How she would presume to know enough to be teaching classes is beyond me; but presume she did. Coming from a computer programming background, her true area of innovation was in programming the Bernina Artista 200 to do fancy embroidery stitches. Fine and dandy, but really all she accomplished was shamelessly plugging Bernina products. Much to my consternation!
So what, ultimately was so misguided about her presentation? Well, for starters, she didn't have a clue who her audience was. I've never felt so "talked down to" in years. Because her experience is so limited, she wasted all our time presenting concepts that seemed new and novel to her, but was just the same old stuff. Yes, we all adore Ricky Timms but we don't need to see a half dozen (possibly more!) harmonic convergence quilts. Yipes!
Also, this poor woman seemed to think that she had to show every card in her hand in this single presentation. We covered her entire personal quilting history, plus her experiences working with ElectricQuilt software and other designing programs, plus longarm and free-motion quilting, plus color science plus piecing, plus machine embroidery plus plus plus.........OMG!
Then when she started to go through her "favorite gadgets" basket and show us various Bernina presser feet, I thought I was going to have to run from the room screaming.
All in all, the most educational part of the evening was the lessons learned in reverse: what NOT to do, how NOT to teach, and, most definately, how NOT to leave them wanting more!
