Hi and thank you so very much. I started doing the toile for the jeans in sewing class which took a long time to fit and get right. Each pair of jeans I have made has come out better than the last. I would suggest doing a sewing class and checking out jean-i-us here a Craftsy with Keneth D King - although he takes you through cloning a favourite pair of jeans and he doesn't include flat fell seams - it is a good course and I learned a lot whiich helped me with my jeans. Hope this helps and good luck with yours!!!
