To answer the question first- having a celebrity endorse any product turns me off b/c I find it hard to believe that they use the product. But that may be a bit cynical :D As for Marie Osmond- I remember a long time ago, when I was a new Mom she was too Good Housekeeping had a cute article about how she had a passion for sewing, with examples of things she made. I remember thinking how nice it was that with her hectic life and lots of money she enjoyed sewing.
So maybe she still does?? But I'd rather see Kaye Wood or Eleanor Burns any day.
