Yes, exactly! I think we're on the same page. I folded up the lower side, lower back and lower front pattern pieces. I slid the measuring tape to illustrate how the pattern piece was folded up four inches. If I unfold this pattern piece it measures eight inches longer. I only folded it up four inches. Does that make sense? That was it, I didn't touch the skirt front or skirt back pattern pieces.
I was happy with the length with this adjustment, but whatever works for you. I'm only five-one so this worked for me.
I hope this photo did a better job explaining what I was trying to achieve in words over at Pattern Review. Apologies if I wasn't clear with the review.
