We then started on the leg pattern. Take the fabric and put it on the bias around the leg. Ordinary fabric (non-knit) is stretchier on the bias and it helps with the fit if the fabric does have some give to it.
Adding image that explains the difference of bias and straight.
I was wearing Capri leggings so we pinned it at the top just below the knee cap. This is not necessary but was helpful for my friend who’d never done anything like this since the fabric didn’t “escape” before she put in those first pins. When you star putting in the pins make sure you do it as tight as snug as possible, the tighter the better. You start pinning the fabric in the middle of the back of the leg, just like those vintage stockings has a seam in the back. Start at the top and work your way downwards. As yo get to the ankle the fabric gets more and more wrinkled andyou will have to do the side splits. Those should be made on both sides of the foot approximately where the anklebone protrudes: I’ve marked the proper spot on the image.
