Frequently asked questions

Questions we hear often about bookbinding and repair, plus a few about how this journal and Signature Count work.

How do I know if a book can be resewn instead of replaced?

If the paper itself is still flexible and the signatures are mostly intact, resewing is usually possible. The limiting factor is more often brittle paper than a broken spine — a spine can be rebuilt, but paper that cracks when folded can't be sewn through reliably.

What's the difference between rebacking and recasing?

Rebacking replaces just the spine piece while keeping the original boards. Recasing rebuilds the whole case — both boards and spine — around a text block that's otherwise sound. Recasing is more work but sometimes the boards are too damaged for rebacking alone.

Is it safe to repair a book with a broken spine at home?

Small stabilizations — a loose signature, a lifting endpaper — are reasonable for a careful beginner. A fully detached spine on a book with any value is worth researching further before attempting, since a rushed repair can be harder to undo than the original damage.

Which adhesives are used in bookbinding repair?

Wheat starch paste and PVA are the two most common, often combined. Paste is reversible and gentle on paper; PVA holds faster and stronger but is harder to undo later, which matters if the repair might need revisiting.

Why do older books smell or turn brittle?

Paper made with certain wood-pulp processes breaks down as its acidity rises over decades, which is what causes both the smell and the brittleness. Paper made from cotton or linen rag tends to hold up much longer.

What is foxing and does it need to be treated?

Foxing is the small brown spotting that appears on older paper, generally linked to trace metal impurities and humidity. It's cosmetic in most cases and doesn't need treatment unless it's actively spreading.

How long does a typical hand rebind take?

For a text block of a few hundred pages, a full hand rebind — resewing, new spine, new case — usually runs several bench sessions spread over a week or two, mostly because adhesives need time to dry between stages.

Do paperbacks get the same treatment as hardcovers?

Not exactly. Most paperbacks are glued (perfect bound) rather than sewn, so a repair often means either reinforcing the glued spine or resewing the block entirely and adding a new cover, which is a bigger job than a hardcover touch-up.

What tools does someone need to start basic repairs?

An awl, a few curved and straight needles, linen thread, a bone folder, and a reliable adhesive cover most simple repairs. A sewing frame becomes useful once you're resewing a full text block rather than a single signature.

Can a missing page be replaced without it looking mismatched?

Sometimes, with paper toned to match and text either reproduced or left as a noted facsimile. It's one of the harder repairs to do invisibly, and many binders prefer to note the replacement rather than disguise it entirely.

What does Signature Count track, exactly?

Signature order, expected versus actual page counts per signature, and short condition notes — the collation information you'd otherwise be tracking on scrap paper next to the workbench.

Is Signature Count a replacement for a bindery's own records?

No. It's meant for tracking a project while it's on the bench, not as a permanent archival record. Larger operations should keep their own formal documentation alongside it.

Does Kettlestitch sell repair services or supplies?

No. This is an editorial journal — we write about the work, we don't take on repair jobs or sell tools, thread, or board through the site.
