Theresa has remade several sections of this dress. I always thought that if you followed the instructions you had it made in the shade. But it is not unusual that even having gauge an item just doesn't fit; or certain sections while beautifully photographed just don't appeal in reality. So you make changes. Now you are into designing. Perhaps just for yourself, but designing nonetheless. Theresa had a very difficult time getting that little band of pink near the neckline to line up properly.
Now she is a very experienced knitter and has made herself more than one dress. So if anyone reading this blog has had the same experience, you are not alone. Remaking and redoing is all part of the craft. Relax and enjoy the process.
