All I did was extend the waist length by a couple of inches and adjust the legs accordingly, but it did the trick. I now have two very loud pairs of Pajamas for Me, and I expect to make many more as the days get cooler and I start pulling out the pretty flannels I have stashed away in the closet. Hooray for successful experiments!
So I needed some new pajama pants. I liked the ones I had made but it was hard to keep them ironed for everyday wear, and then they didn't fit quite the way I wanted them to. Their official name is "Pajamas for Everyone" in Heather Ross's Weekend Sewing, but they really don't seem to be for people with hips or much of a waist, so I decided to try out a simple alteration.
