SSE,
Sewing the leggings in the picture wasn't all that hard. The stitches I used were a bit longer than I wanted but still hold the leggings together. For me, the hard part was re-learning the blanket stitch used on the edges of the leggings to keep them from fraying. I'd used that stitch 30 years ago when I sewed a capote, but hadn't used it since. Although once I got the hang of it, doing the blanket stitch was easy. The other thing wish I could do over was my choice of yarn color. I used yellow and sage green, thinking that would be a nice contrast. Unfortunately, the sage green does not show up well at all on the grey blanket. I should have used a forest or darker shade of green. I had originally planned for every other stitch on the leggins to be yellow and green, which I thought would make a nice contrast. But had to change at the last minute. If you look closely at the picture, you can see some of the green yarn along the edges of the leggings.
Making the pattern for the leggings was a different story though.
I'm working on gradually building up my skills to one day try to hand sew an 18th Century shirt. Each project I'm doing tries to build on my skills. My first project, after my 30 year hiatus, was a simple rifle sock . Then the leggings. Now I'm sewing up a canvas haversack. The haversack requires a bit more attention to detail as far as measuring, stitch size and placement.
