He's going to Blizzcon in October and wants to dress as a human form Worgen. Since it's a gaming con, though, he needs a bag to carry his junk around, and a standard, canvas bag really wouldn't do.
And because I can't help but make things more complicated, I offered to make the bag reversible, so it was wearable with more things.
I found this excellent tutorial Which I then tweaked till it worked for a reversible bag. Because the silk was thin, I lined both sides in heavy fusible interfacing, which really stabilized everything. I also added a line of stitching around the top of the bag and the flap to keep it in place, even after some hard use.
Still.....I'm quite pleased with the outcome.
