While toiling over pants fit way back in February and March, I copied the yoke front and back pieces, along with the dart placement for Vogue 8751. I then copied the pattern pieces onto Glad Press N’ Seal for easy placement on my muslin pieces. Thankfully, I took a photo of the front’s adjustments according to my personal fitting. The photo’s darkened here to show detail.
Once I got the darts and yoke placement down with respect to my sloper, I made copy from cheap gift wrap. Here’s the back piece I was working with when the trouble began.
Here’s where I went wrong with the back length outseam adjustment on the black pair of V8751:
This would have been a better solution, and what I did to adjust the other three pair I had already cut.
I’m sure there are other, better ways to make this adjustment, but after all the adjustments to the sloper this as safest for me. Happy sewing everybody!
