So, nope, I didn't manage to make the pattern for my sleeves last night. However, I did do a little reading, and found a shortgown in Costume in Detail that is kind of similar to mine, and I determined that the sleeve should be a 1-pc sleeve (I was going to make an older-style 2-pc sleeve). That is a little bit of progress, right?
I also pulled my picture from my last post into Illustrator today to work out where I want my armscye to be. While I was there, I mocked up an embroidery idea for the CB panel - I can't actually change where my shoulder and side-back seams are, but I can maybe create the illusion of a proper narrow back with some chain-stitched embroidery (similar to what is seen on the back of this dress.)
Also... the width of the front is now really bothering me. I think I will have to chop it out! (you can see about how much I would take out as delineated by the white block on the picture below).
Lots to do tonight!
