Later on today, after making a run to get some more glue sticks, I was able to FINISH!! I glued the rest of the pieces on, and tacked on the thing that goes on top of the hood. There goes my resolve not to hand-sew anything. I was gonna use velcro, but it wouldn't get all sides. So I just stitched a little around the corners of it so it would stay down. A few other stitches here and there, and wah-la! Finito!
Since I beat my goal of having it done by the end of this weekend (the 2-week mark), maybe I'll take off until Monday to start the second costume. Maybe.
