Silksong collectibles · 18 spool fragments

Hollow Knight Silksong Spool Fragments — All 18 Locations

Spool fragments are Silksong’s silk-bar upgrades: every fragment you collect permanently extends Hornet’s spool by one notch, and a bigger spool means more silk for bindings, healing and tools. Eighteen are scattered across Pharloom — most tucked into secret rooms, with at least one sold by Grindle once his shop opens.

The tables below group all eighteen by act, and every row deep-links to the exact marker on the Silksong interactive map.

Silksong spool fragments in order

Fragments follow the same rhythm as the rest of the run: a handful in the Act 1 lowlands, the bulk inside and around the Citadel in Act 2, and the last few in the endgame regions that only open in Act 3.

Because most fragments hide in secret rooms, sweep each region’s walls and ceilings before moving on — and if one slipped past you, the map filter below narrows the search to a single region.

Act 1 — 5 spool fragments — Moss Grotto, The Marrow, Deep Docks, Far Fields, Greymoor
Act 2 — 10 spool fragments — Bellhart, Shellwood, Blasted Steps, Bilewater, Wormways, Sinner's Road, The Slab, Whiteward, The Underworks, Choral Chambers
Act 3 — 3 spool fragments — Whispering Vaults, Mount Fay, Verdania

Spool fragments before Act 3

The silk bar carries straight into the endgame, so it pays to finish the set early.

No spool fragment is currently flagged missable. The dataset marks every placement for verification, but nothing is locked behind a one-time event like The Slab escape — the full set can be finished in any act.

FAQ

▸How many spool fragments are in Silksong?

Eighteen. Most hide in secret rooms across Pharloom, and at least one is sold by Grindle in The Marrow once his shop opens.

▸What do spool fragments do?

Each fragment permanently extends Hornet’s silk bar by one notch. More silk means more heals, bindings and tool usage before you need to top up again.

▸Where can I buy spool fragments?

Grindle sells spool fragments from his shop in The Marrow once he is freed. The rest of the set is found in secret rooms rather than bought.

▸Spool fragments vs the Spool Extender — what’s the difference?

They stack. The eighteen fragments each add one notch, while the Spool Extender tool adds four extra notches separately — collecting both gives Hornet her largest possible spool.

▸Are any spool fragments missable?

None is currently flagged missable in our dataset. Placements are still being verified against the interactive map, but no fragment sits behind a one-time event — the full set can be finished in any act.
