I carried on with my jeans today. I added the front pockets and then did the fly front. I'd found a You Tube video which showed a much better way to do it than the patterns way. I'd also left myself a cryptic message on the pattern to not use the patterns method but to use the one from the fold trouser. Completely befuddled as to what I meant by the fold trouser!!
Anyway it was a very good method and the front worked out beautifully. It's on a channel by The Last stitch 'Sew a perfect jeans zipper'. I watched and made notes and then did it for myself.
I then sewed the inner legs but gave up at that point as my eye was sore.
Hopefully I'll get some more done tomorrow.
