As I am drafting the first bra (while writing this review) - 3.1 The basic underwired bra pattern, I just discovered the C.F to B is incorrect.
It says Step One: C.F. to B = Half of the sternum + wire width + 3/4" + 1". Figure 1 shows C.F. to B equals 5 5/16" - 6 5/16, (if the sternum width is what this refers to the sternum width is listed as 5/8"-3/4" on page 8, which would be incorrect math).
So, I used the half the across front (A.F.) measurement of 12 for the 34B (size 10, full bust girth 34), (assuming this must be the correct measurement to use); but it is still incorrect, (12 /2+ 3/8 + 3/4" + 1 = 8.075; Which is not Figure 1 calculations). The editor's/publisher doesn't have a correction listed for this. So, I'm not sure what measurement is being used. Accuracy is a must in pattern drafting. This is aggravating!!!! I'll post an update when I complete the draft.
