I'm starting with the Charné 80DD after all

I slept maybe 4 hours before waking up excited about the package I'll get from the post office, and about making alterations into the pattern. Since I woke up I've traced the pattern in 80DD as well. Last night I fell asleep thinking about the changes I need to make into the pattern (here I was thinking of using the 80D as a starting point):

However, now I think that I will start with the 80DD. It is probably easier to see how much needs to be taken out and what the fit is with a better back band (I assume that the back band in 80DD will be better for me even though the edge still needs to be slanted a bit, I feel). I'm also assuming that the cup itself in the 80DD will be a bit too big - in that case I will trace a mid-level pattern between D and DD (I will need to understand how the distance to the edge of the breast is calculated - that I will probably not need to decrease even though I need to decrease the cup volume).

Before making any alterations I will sew the 80DD as it is, and then make alterations with the help of the Bra-makers manual. I'm thinking that I will need to refer to the sections titled "Band Gaps Along Upper Edge Close to Wire Line", "Bridge Is Too High Or Too Low", "Cup Volume Is Too Much" (although I'm very disappointed with this section! It only says "start with a smaller cup size".), "Lower Cup Is Too Deep", "Wire Line Needs To Be Wider At Underarm", "Making The Bra Lower Under The Arm".... I might need other sections as well, depending on the fit of the bra.

I'm somewhat apprehensive about the shape of the front band, since I'm afraid that it's not wide enough for my breasts. But I know that I can make alterations to it, and find a well-fitting pattern after a while!
