I did this as a VERY last minute cosplay (what else is new :p). I finally made the bag in an all night session with my sewing machine. It was painful and I didn't leave myself enough seam allowance and it came out awful!!! The bag is currently in pieces right now. I'm going to make my own piping and try to preline the bag instead of doing a drop in lining. I pray that I'll have it all done in time for the next New York Comic Con. It was great doing the cosplay there! A lot of people recognized who I was and I got to meet Brian Lee O'Malley (again... I actually did meet him once before, but that was before my boyfriend got me into Scott Pilgrim. He's insanly shy in person. He seems a lot friendlier if he responds to you on the internet.)
