The back panel in the dress became a problem because in the fitting the panel needed some kind of dart. So I created the dart to look like it was in between the two changes of color in the fabric.
I did another fitting with her and it was puckering out funny. So I decided to redo the pattern by taking the back panel and tracing around it on paper. that way I have the shape of the pattern I need without a dart. It worked perfectly.

After doing a muslin mock-up and fitting, I cut out of the fabric and started to assemble the dress. As you can see the back piece is missing. The next post is going to talk about this.
