The other pair, which I never got around to photographing, are black, and made in a 90%cotton/10%spandex blend I bought at JoAnn fabric. They are the overbelly waistband version, and they have the perfect amount of stretch. They were super comfortable and I wore them under dresses to work, church, and everywhere else at least twice a week.
Off the top of my head, I don't remember what size I made. It was whatever the pattern suggested for my hip measurement. I do know I lengthened them by 2.25", divided evenly at each of the three cutting lines as suggested in the pattern (I'm 5'10", and if I remember correctly the pattern said it was graded for a 5'5" woman). The size was correct widthwise and the length was perfect.
In the interest of not wasting fabric and I always need undies, whenever I cut out a cotton/spandex knit garment I cut as many pairs of Seamwork Geneva undies as I can from the scraps. Between the scraps from these two pairs of leggings, I think I have 6 or 7 pairs of undies that I haven't sewn up yet. We'll see if I get to that this spring/summer (or Me-Made-May?) - with two kids now, it will probably take me a while to figure out how to fit sewing time into my new routine.
