At this time, I stitch together the three sections of the front pant legs. I kind of need to pay attention as to which center piece is which, and which way is up. Other than that, pretty straight forward.
Here, I have gathered the knee pieces before stitching to the upper and lower pant leg pieces. In hindsight, I should have stitched all three sections together and then run the basting stitch along the sides of each of the middle pieces. That way it would have been much easier to ease the pant leg fronts to match the pant leg backs in a later step. So, do as I say, not as I do: Stitch all three sections together, run a basting stitch along the middle pieces and gather later to match the pant leg fronts to the pant leg backs. Alrighty?
And, this is the time to add any trims that should join in the inseam and outseam. No such thing as too many trims.
