For the next stage of creating my toile I had to insert the tight fitting side panel into the trousers.
This has been the most difficult part of my trousers so far as i had to notch and pull the side panel into place as it wont fit properly without. When this was done I was able to sew and and think that it has turned out really well.
After putting my toile on the mannequin I came to the conclusion that the side panels weren't tight enough, so I went back to my patterns and took 2cms off each side.
I will see if this works when I insert my next side.
