I made this within the hour of buying the magazine. It turned out terrible because I cut the neck opening to large. I decided to try again. It turned out Marvelous!!! I am now working on a third, it is finished but I want to add embellishment to the neckline. When making your squares you need to go back to basic algebra and calculate based on the triangle formula. A^2+B^2=C^2. A and B are equal and C = your widest body measurement. Now you get 2A^2=C^2. Find the measurement for A. Divide A by 2 and now You will have a small square the correct size. Add SA. The large square is 2x the size of the small one without SA and then add seam allowance. Hope this helps. I have been messing around with bias for a while now and so I knew how to figure my square sizes. I like the idea of adding a band around the bottom for a longer length. I want to know how you got the length for the sundress???
