ARRRGGHH - all of the above bad habits but the big one is not taking the time to calculate yardage correctly when i start drafting my pattern. I either overbuy or underbuy fabric and either cut too many strips (boy I am going to have some GREAT scrap quilts IF I ever get around to making them!) or not enough strips which means I have to stop in the middle of piecing and cut more. I have been wanting to try a Bargello quilt but based on the above bad habits I'm terrified to try!
