The house is starting to heat up and it's making me cranky

Yesterday I found an error in the bag pattern I've been testing! The
intersecting seams for the back are the wrong length. I forgot to true
seams for the front and back panels or I would have caught it. I've fudged
it on the muslin so I can finish checking the assembly procedure. After
this I'll be way better at sewing intersections; maybe I'll do another
godet skirt next.
