Step 7Finishing the signatures
iImage Information

When you've sewn all the signatures together, double kettle stitch the final head or foot. Then take the PVA and squirt some onto your finger (or a paintbrush, but you finger works better and it's fun to peel off the glue) then rub it *into* the spine. It is important that some (albeit just a bit of) glue gets in between the signatures and fills in the spine. When this is done, cut a piece of cloth (not bookcloth) to a little bigger than the dimensions of the spine. Stick this onto the wet glue and smooth it out. Then cut a piece of heavy cardstock to the exact dimensions of the spine and glue it onto the cloth. Rub it smooth.
NOTE: During all this, make sure the bindings are centered and sticking out! I once clipped one off while trimming the card, so be careful.
