No, No, and absolutely NO WAY NNNNOOOOOOO!!!!!! I realize that I am in the minority but experience has taught me that my accuracy of anything----cutting, drafting, sewing, you name it----is at best unreliable and at worst, downright comical when I'm upset. However....I will design something new if I'm in the mood (usually not!) but then I mark it with the date and the mood I was in, and a note to self to doublecheck absolutely everything before ever starting it!
