You make a great point: Quit putting yourself down by saying this!
I agree with you but it helps to let people know that you think you should be able to do something when you feel everyone else obviously has mastered it:) I have been messing around with sewing all my life and feel i should be further along. I know I'm not stupid and neither are my questions but it's a "stupid" habit I have of prefacing every question with "I got a stupid question."
