She didn't come across as condescending or mean spirited in her post. I believe she was only pointing out that a person isn't going to magically become Michelangelo in front of a sewing machine without practice.
I realized, from her post, that I can't draw with a crayon so what in the world would made me think I could do it with a electric machine and a needle going at 1000 stitches per minute?! The ability to draw has to make the flow easier, my brain doesn't work that way. I've said before "My brain creates a masterpiece, my hands make a mess."
