I scored the margins of the print pages
before affixing the tissue interleaves with Filmoplast, an acid-free tape.
I realised I also needed to score the margins of the portfolios, and mark the spots where the binding holes would be drilled (an awl can be used, but a drill press is faster and less fiddly).
After the holes were drilled small bits of wire were put in place to ensure that the pages would not move during binding.
Japanese stab-binding (full instructions here) is both simple and elegant. I chose a teal cotton embroidery thread (6 strands) to complement the colours of the prints.
Once everything is in place, the binding doesn't take long.
