I was a bit scared of this sewing part. I just knew that I'd muck up punching the holes. And I did - I did them upsidedown (which meant they were placed wrongly). But I was able to burnish over the holes to hide them because of the thickness of the pink paper, and re-punch them easily.
The actual sewing part was actually pretty easy.

I was very pleased to make first use of my awl, book sewing needle and waxed linen thread.

I was very confused why the hinge was facing backwards, until I worked out that when the hinge was all folded up, the pattern on the paper would face outwards, as the spine of the book. Aha!

The scans aren't very good, coz the book is now a bit too big for my scanner. And it's going to get worse, because the book is about to go 3D, and I don't have a camera. I'll have to get Sal to take some shots.

So this hinge folds up, and voila! A book! My bone folder has been of immense use during this project.

There is an extra "panel" at each end of the hinge. This extra panels are about to get glued onto the book covers.

This scan is even worse, but it does show the extra panel at the top, (er, right hand side of the book), and you can see the front page of each of the 3 signatures (sets of pages), sewn at intervals along the hinge.

I also used foil for the first time to write "Sally's Photos". It's lovely and purple and bright. Heavy use of metallic crayons as well. I like metallic crayons.
