I've just made my first pair of playtime leggings, I love the pattern! Less than an hour sew :)
I sewed the 6 to 12m size and the diameter of the waist opening seems very small, like about 14". This seems very small when the waist (on the body) measurement is 19.5". There is no finished waist measurement for the leggings, however the out seam value is the same as the length of the leggings I sewed. I'm sure I sewed a 1/4" seam allowance. Unfortunately I don't have a baby to try these on, they were going to be a gift.
Has anyone else sewn the 6-12m legging? How did they fit?
