The Pendrell is much less intimidating. After reading FFRP (again & again), consulting my body graph, and making the following notes, I feel prepared.
My biggest challenge was doing the math to figure out the difference between the pattern measurements & my own. :) Subtracting fractions is not my strong suit. Thank goodness for Google, that's all I have to say.
After that I set out to draw new cutting lines. My cutting lines started out at 5/8" at the shoulder & tapered to 0 at the neck. This will fit my high left shoulder. For the right shoulder, I am just going to lower my stitching line another 3/4". I then lowered the armhole, using my nifty Project Runway Design Ruler.
I was going to stop there, but I decided to do the Broad shoulder alteration. It's a straightforward alteration, but the illustration in FFRP shows that you only add width to the front side pattern piece on a princess seam. Now, I know I'm new at this whole thing, but it didn't really make sense to me, so I added it to the back side pattern piece as well. (Tasia agreed that it needed to be added to both front & back; though she did point out that the ruffles will cover the shoulder) We'll see how that turns out.
Also, I decided to adjust the neckline a bit. The blouse has plenty of easy to just slip on, but I wanted to be sure to have plenty of room to get my (sometimes big) hair through the neck hole. I lowered it a 1/2".
Here's what my shoulder slope alterations looked like. In these pictures I've just drawn the new cutting line.
And this is the broad back alteration. I will probably true the seams a little better. Even with using the French Curve, I think that they could be a touch smoother.
So. There you have it. Today I will cut out the fabric for my muslin. I was initially planning on doing one without hte sleeve ruffles, but I think I'm going to do one with (if I have enough yardage) and shoot for a semi-wearable muslin. Time will tell!
