I'm starting with an original pattern from 1907 (that's the crazy multiline picture!), so I just know it's going to need some fixing. I copied the pattern pieces and scaled them up in CorelDRAW, then made a few alterations to get it to approximately my size. I'm not going into details of that here, but you can get an idea of how I work with patterns in CorelDRAW from my instructable on adding seam allowance
, and my one on converting paper patterns to laser-ready files
. For this paper mock up, I've left my seam allowance lines showing, and I've drawn in my waistline and notches for matching. You'll see why!
I've printed it out full size using the large format printer, then cut out each individual pattern piece.
