This was really more of a prototype or model to learn the structure. It doesn't look like a finished book to me, probably because it doesn't have a separate cover, just the cover stock that covers the individual signatures. But the structure is interesting and I'm glad I made it. And I think a couple of days under heavy weights will improve it dramatically.
The recessed skewer structure comes directly from Shereen LaPlantz very useful "The Art & Craft of Handmade Books." Lots of good structure ideas and examples in this book.
This hand made book has seven signatures in various colors, The pages are text weight and each sig has a cover in cardstock of the same color. Inside each nested signature is a bamboo skewer. The stitching goes in a hold from the outside, around the skewer and out the same hole, then on to the next sig. I then doubled back, stitching them all again with a coptic-style chain stitch and really snugging up the tension. It's still a bit loose and not lying very flat. It probably needs some sort of overall cover and/or a closure of some kind.
Anyway, here it is. On to something else tomorrow...
