Thank you so much to K Krewer, Carolann Schmitt and Beth Chamberlain for sharing photos with me on the bertha. I've decided to go with the split bertha for no particular reason than I think it will be easier to do...lazy, I know.
Here is the completed mock up; please keep in mind it is only basted together so nothing is really laying right on the form and nothing is hemmed. It does meet in the back, I just didn't pin it close enough. I'll need to try it on me with the corset in the next few days.
