Look at this! Buttons and pockets, oh my! I even had to do some measuring! Though in the end, I don't think the measuring was necessary. I think perhaps the tutorial was a little more involved than it needed to me. I had to use a ruler (shocker!) to measure and mark the bottom of the bag, just so that I could accurately make the box corners. Just seemed a bit overkill, but I suppose some people like to be very precise. You might have figured this out, but when it comes to sewing, I'm not precise at all! LOL!
