Sew-a-long Snag

Well, I was doing pretty good on my Brandt's Boulevard Wallet from Chris W Designs. And then I had to topstitch.... Oh well, unpicking stitches is good for character building, right?
  These are all the pieces - I thought THAT was going to be the hard part!
 Here's the outside.  I was so excited that things were going well that I didn't take a picture of the inside before sewing the pieces together.  I think I'll have to turn to my antique Singer for the final steps.
