Trying a pants fitting kit - Sure fit designs - trouser fitting

Hi everyone, today I'm showing you an update with making trousers for myself. I have the Sure fit designs pants kit and have tried it out, but things are not so straight forward. I have had problems sewing the leg seams as they don't run straight, so have been trying to tailor the trousers to my legs. I think the crotch curve is accurate, but making pants is not very easy, especially if you don't have a fitting buddy to help you with your sewing.
