Now that my toile is finished I need to make any adaptations to my patterns. In my case I need to make my outer later patterns 2cm bigger to add more volume and taper them in at the bottom.
First I added the 2cm all the way around the piece.
Then I measured the ankle and took the difference between this and my pattern piece of each side equally. Then I gradually extended this back to the correct width.
I then repeated this with the other piece.
When this was done I could cut the pieces out of my final fabric.
