I hear ya! It seems I get suckered in every time!
Will you make curtains, will you hem my pants, will you mend this hole, will you alter my bridemaid's dress, my prom dress....
I just had a guy ask me if I could alter his suit jackets because he had lost a lot of weight! Yikes! That one had to go to the tailors!! People think we can do it all!! :)
