Who is it here in the forum who tells the story of her knitting guru, and how when she was first knitting, she complained that her stitches didn't look right, and the guru responded with something like "You've just started, so how do you know what 'right' looks like?"?
I'm sure I don't have that exactly right, but you get the idea! Besides, (and I've tried myself and paid for it), we cannot possibly compete with the even stitches of machines! Let your work be flavorful
And I'm glad to hear that the videos have helped you and that you've loosened up. Your fingers, wrists, shoulders, and neck are probably thanking you already!
