For my second pair of jeans, I watched Angela Wolf's craftsy course "Sewing Designer Jeans". I watched it all the way through. I then meant to follow along as I sewed my jeans, but my internet was down that day, so I had to go from memory.
I used denim that I had bought half price from Lincraft, and treated this as my second muslin, as after all my fussing about on the first pair, I wasn't certain where my final crotch shape ended up.
This pair will make its way to the op shop, but I am not upset, because I got to practice my top-stitching and distressing, which both got a lot better by the end of these. These are also my best belt carriers ever. (My daughter is reading over my shoulder now, and she is amazed that I would discard them as she thinks they look better than my other pairs...but looks versus ability to walk, and I will take walking every time.)
