Lost in Silk Kingdom’s shadows? Those elusive spool fragments hold the key to Hornet’s silk upgrades-pinpoint every one here.
All spool fragment locations in Hollow Knight: Silksong
Spool fragments hide across Silk Kingdom’s regions, waiting for collection to craft the Weave. Pharloom’s shadowy corners hold early pieces near entry points, while overgrown paths in the trees yield others after puzzles. Deep dives into flooded caves reveal submerged ones, and high ledges in windy cliffs drop more upon precise jumps. Track all 20 by checking maps after boss clears, as some appear only post-progression.
Silksong has 18 spool fragments scattered about Pharloom, and for every two fragments you find, Hornet’s spool can hold a bit more thread. After acquiring all 18 fragments, you can hold enough silk to let Hornet bind twice when the spool is full or use silk skills more frequently. That makes more of a difference than you might think during challenging boss fights, so it’s worth tracking all these down before you start Act 3.
Spool fragment #1 – Mosshome
You’ll need to enter Mosshome via The Marrow’s upper left exit, via the passageway above where you find Shakra. Exit the chamber at the far left, drop down onto the platform, and activate the elevator for easier access to Bone Bottom if you need it. Hop across the platforms to your right, and make your way up. Break the wall under the rosary cache, avoiding the traps as you can, and enter the next room, where you’ll find the spool fragment.
Spool fragment #2 – Above the magma in the Deep Docks
Enter the chamber shown above, and hop your way across the magma. Hornet won’t take damage from it unless she stays still, so if you continue jumping, you’ll be fine. At the far end is a lever. Hit it to move some of the hanging platforms around, and then hop your way back across, using the platforms to reach the ledge on the left side of the room to find a spool fragment.
Spool fragment #3 – Greymoor
In the chamber to the right of the Far Fields entrance, clear the arena battle in the house on the lake to release a bundle of balloons. Then, make your way up the balloons by pogo jumping off them. If you’ve accepted the “Craw Clearing” wish from the Halfway House barkeep, this is a good opportunity to collect some Ragpelt as you go. At the very top, in an alcove on the left, is the spool fragment.
Spool fragment #4 – Bellhart
You can purchase a spool fragment from Frey the merchant in Bellhart for 270 rosary beads after defeating Widow and completing the “Threadspun Town” quest.
Spool fragment #5 – Weavenest Atla
Use the Needolin to open the Weaver door at the eastern end of Mosshome, and progress further in to speak with Eva. Once the conversation ends and you can explore more of the nest, use the teleporter to reach the bottom of the area. Wall jump onto the ledge above the nest’s elevator, go left, and deal with the large enemies. You’ll find this fragment above the water.
Spool fragment #6 -Flea caravan in Blasted Steps
After you move the caravan from Greymoor to the Blasted Steps just outside the Grand Gate, where you fight Last Judge, Mooshka the Fleamaster rewards you with a spool fragment. This can only happen after you’ve entered the Citadel and begun Act 2, and you need to find 14 fleas in total before Mooshka moves the caravan from Greymoor.
Spool fragment #7 – Grand Gate
Climb to the upper left corner of the Grand Gate by using the platforms (you can hit them from underneath to adjust their position) and claim this fragment in a small chamber.
Spool fragment #8 – Below the Ventrica in the Underworks
Exit the Underworks Ventrica station and drop down, avoiding the steam as you go. Enter the room on the left to find the spool fragment and a shortcut to the western half of the Underworks.
Spool fragment #9 – Below the spikes in the Underworks
Enter the Underworks via the elevator from The Stage where you fought Trobbio, and go left. Carefully work your way above the spikes, until you see an opening in the floor. Hover into it, and at the bottom is a little walkway leading into a rock. At its end, you’ll find a spool fragment.
Spool fragment #10 – Cogwork Core
The Faydown Cloak isn’t necessary for this one, but it certainly makes things easier. From the Cogwork Core bench, drop down to the bottom of the room, and hop along the platforms to the right until you reach a room in the bottom right corner. Enter, wall jump up the shaft, and hit the lever multiple times to open the door. A large clockwork bug will appear, but you can ignore it and duck into the newly opened path. Hit the lever there to open a trapdoor, then follow the tunnel to find a spool fragment.
Spool fragment #11 – Under the elevator in Whiteward
Getting this spool requires a bit of acrobatics, as it’s at the bottom of the elevator shaft in a spot normally covered by the lift carriage. Take the elevator down in Whiteward, and then go left. The path eventually leads you up and back around to a corridor that opens onto the elevator shaft. Wall jump your way up, and stand on the button to call the elevator, then immediately drop back down and enter one of the corridors on either side of the shaft. Wait for the elevator to pass, drop down to the bottom, and grab the spool fragment.
Spool fragment #12 – ‘Balm for the Wounded’ quest in Whiteward
Sherma eventually makes his way to the Citadel and winds up in Songclave. You may need to visit the Choral Chambers spa first and see him there before he appears in Songclave, but either way, complete “Building Up Songclave” by donating 300 rosary beads at the First Shrine’s wish wall, rest at a bench, and then speak with Sherma.
He should mention concern for the suffering pilgrims, at which point Hornet recommends he do something about it aside from just praying. Leave the area, rest at a bench, and return, and Sherma should be gone. On the wish board is a new quest, “Balm for the Wounded.” Sherma is in Whiteward, in a room above the mortician enemies. Enter the room and defeat the three waves of enemies. Sherma thanks you for your help at the end and rewards you with a spool fragment.
Spool fragment #13 – High Halls
After you climb the first waterway and enter the vertical chamber beyond, you can go up or down. For the fragment, go up, using the Faydown Cloak’s double jump. Use the Clawline to grab onto rotating rings, avoid or fight the minister enemies as you come across them, and at the top, break the glass dome and grab the spool fragment.
Spool fragment #14 – Mount Fay
You’ll see this fragment from Mount Fay’s main, open area, though Silksong treats it like part of The Slab (probably because it’s only accessible from The Slab). From the Bellway station, go up, and enter a duct via an exit in the roof. You’ll enter a narrow corridor that only leads left and spits you out where the spool fragment is. If you don’t have the Apostate Key from the Putrified Ducts, you can access this fragment via The Slab’s Choral Chambers entrance.
Spool fragment #15 – Songclave
After you complete “The Wandering Merchant” wish and donate 500 rosary beads to Songclave for the “Strengthening Songclave” wish, Jubilana goes missing again. Accept “The Lost Merchant” wish from the Songclave wish board, and then find her in Memorium. Once she’s back in Songclave, she’ll sell you a spool fragment for 500 rosary beads.
Spool fragment #16 – Hidden cave in the Deep Docks
This one’s a bit of a doozy, and you need the Clawline to make it work. The Faydown Cloak helps as well, though it isn’t essential. Enter Deep Docks from the breakable wall in Far Fields’ bottom left corner.
Drop down, go left, and enter the large chamber. Drop down again, carefully to avoid the lava, and land on the right-most platform. Jump and use the Clawline to reach the wall on the other side, then navigate through the cave of spikes using Cling Grip and the Clawline.
After clearing the spikes, cling to the left wall for safety, and jump and glide toward the red blossoms. Pogo off them, cling to the right wall, and attack the glowing spot on the ceiling to make another path. Use the Clawline to navigate this next path of spikes, and at the end, strike the glowing spot on the floor to open the rest of the path. Follow it around, and it’ll eventually drop you out at the spool fragment.
Spool fragment #17 – Grindle in Blasted Steps
Grindle sells you a spool fragment for 680 rosary beads. However, you’ll need the Faydown Cloak to reach the room where he’s set up shop, as it’s impossible to reach the wall and climb your way up without it.
Spool fragment #18 – Memorium
The Memorium spool fragment is locked behind a platforming challenge. Make your way through the region, climbing up and circling back until the path lets you out in a vertical chamber. Enter the room below the Ventrica station, and drop down the shaft. Activate the Drifter’s Cloak before reaching the bottom to avoid the thorns and enter the room on the right to find a passageway full of thorns. Use the double jump or Clawline to clear the first hurdle, then float down, and cling to the thornless wall on the right. You can use the Clawline to move left and then double jump to reach the next safe point, or jump, dash, and double jump – whatever’s easier for your playstyle. Dash off the wall to safety, and grab the spool in the next room.
Best route to collect all 18 Spool Fragments quickly
Hollow Knight: Silksong has 18 Spool Fragments scattered across Pharloom, with an efficient route prioritizing early Act 1 access, Bellway shortcuts, and minimal backtracking.
Early Route (Fragments 1-4)
Start at Marrow Bellway in Mosshome, head west to Bone Bottom for Fragment 1 via the southwest passage above Shakra. Next, travel to Deep Docks Bellway (east side) for Fragment 2 down the lava shaft from the central bench. Swing to Greymoor entrance for Fragment 3 using balloon platforms and Drifter’s Cloak. Finish with Weavenest Atla (Fragment 4) via basic exploration.
Mid-Game Progression (Fragments 5-12)
After story progress in Bellhart, complete “My Missing Courier” Wish for Fragment 5. Cycle Songclave Wishes (“Wandering Merchant,” “Lost Merchant” with Jubilana in Memorium) for Fragment 6. Do “Balm for the Wounded” with Sherma (Whiteward) post-Songclave buildup for Fragment 7. Grab Fragment 8 in Whiteward elevator shaft, then Underworks bench east for 9 and 10 (gauntlet room, spike pits). Advance to Cogwork Core (11) and Memorium (12).
Late Collections (Fragments 13-18)
Get Fragment 13 in The Slab prison by reclaiming gear pre-freeze. Blasted Steps Bellway yields 14 with double jump. Deep Docks second spot (15, Clawline needed). High Halls Clawline path for 16. Save 15 Fleas for Flea Caravan at Blasted Steps (17, post-Flea Brew quest), then defeat Last Judge at Grand Gate after activating 5 Bell Shrines for 18.
Optimization Tips
Unlock Bellways (Shellwood, Underworks Ventrica) early; use double jump and Rosaries for precision jumps. Follow video timestamps from comprehensive guides for visual paths, aiming for Act 2 completion.
Which Spool Fragments require specific abilities first
Several Spool Fragments in Hollow Knight: Silksong require specific traversal abilities beyond basic movement, often unlocked progressively through Act 1 and Act 2.
Act 1 Requirements
Greymoor’s east fragment demands Drifter’s Cloak for precise platforming on balloon platforms and exploding walls. Deep Docks’ second fragment needs a Simple Key for later access after initial exploration. Bone Bottom uses early glide/dress mechanics over lava platforms post-switch activation.
Act 2+ Abilities
High Halls fragment requires Clawline (grapple) for elevated paths. Blasted Steps needs double jump for precise gaps. Whiteward elevator and Underworks spike pits rely on Cling Grip and air dash for shaft navigation and obstacle destruction. Grand Gate’s Last Judge fragment mandates activating 5 Bell Shrines first.
Quest Dependencies
Fragments from Bellhart (“My Missing Courier”), Sherma (“Balm for the Wounded”), and Flea Caravan (15 fleas saved) tie to story progress rather than abilities alone. The Slab prison piece requires reclaiming gear during a capture sequence before freezing.
