I have it set up so that by typing in one (ONE!) number and adjusting the fields at the top it will pretty much fill in the other numbers. The bright orange columns are where I tweak neckline, armhole and cap shaping. I can’t figure out how to database this without taking about a month off, so the quick and dirty spreadsheet is my friend!
(my favorite feature is the formula I wrote that outputs all of the info in each column as, X (Y, Z, A, B, C, D)” / P (Q, R, S, T, U V) cm)
