So I've got quite far with my dress now and can finally see the end in sight. The next step is to attach the facing. So I went to my draw as I had already cut out my facing piece but it wasn't as simple as just attaching it because when I looked at my panel I realized that I hadn't cut it on the fold so I went back to my fabric to cut another but I then realized that I didn't have enough to cut it on the fold so I had to add seam allowance to my pattern and cut out two separate pieces that will be sewn together.
When I had solved the problems that I had with the facing I was able to attach it. But I could only attach it at the front as I needed to remember that I have to fit my dress to the model and insert my straps once they had been put the the right height for the models shoulders.
