The smocking plate is from an old Creative Needle magazine with some modifications. It was originally meant for a basic yoke dress-- which would mean it would not have enough stretch at the lower side for the bishop dress.
I barely had enough fabric for the dress so I was only able to make a 2 inch hem. Normally, I prefer a 4 inch hem. I know some people even prefer a 6 inch hem in heirloom sewing. Really, the important thing is that i was able to make the dress with Emma Kate's fabric choice.
