How to Get Silk — Step by Step
Collect Cobwebs underground
Cobwebs are the white sticky strands found throughout underground caves, abandoned mine shafts, and Spider Cave biomes. Unlike most resources, you do not need any tool to collect them — simply walk or jump through them and they are automatically added to your inventory. Each Cobweb tile you pass through gives one Cobweb item. They also slow your movement slightly when you walk through them, similar to walking in water, but this does not affect collection. You need 7 Cobwebs per Silk, so plan accordingly.
🕸️ Walk through Cobwebs to collect — no tool requiredFind Spider Caves for bulk farming
Spider Caves are the best Cobweb source in the game. They are small dark caverns that spawn deep in the Cavern layer, completely covered wall-to-wall in Cobwebs with Black Recluse spiders crawling throughout. A single Spider Cave typically contains 50–100 Cobwebs, giving you enough for 7–14 Silk in one visit. Look for pitch-black biomes on your minimap with no light — Spider Caves do not have any natural light sources, making them visually distinctive. Bring Torches and be ready to fight Black Recluses.
🕷️ Spider Caves: deep underground, fully dark, 50–100 Cobwebs per caveBuild a Sawmill and then a Loom
Silk is crafted at a Loom, which is built at a Sawmill. Build order: Work Bench → Iron Anvil → Sawmill (10 Wood + 2 Iron Bars + 1 Chain at Work Bench) → Loom (12 Wood at Sawmill). Place all three stations near your crafting area. The Loom recipe is straightforward and cheap — just 12 Wood — so once you have the Sawmill the Loom takes about 30 seconds to build and place.
🧵 Loom = 12 Wood at Sawmill — place it next to your other crafting stationsCraft Silk at the Loom
Stand next to your placed Loom and open your inventory. Find the Silk recipe in the crafting panel — it requires 7 Cobwebs per 1 Silk. Click to craft one at a time, or hold the craft button to craft in bulk. The conversion is purely one-directional — Silk cannot be broken back down into Cobwebs. For a Bed you need 5 Silk (35 Cobwebs total). Craft a few extra Silk beyond what you need immediately since it is also used for various vanity items and the Rope Coil recipe.
✂️ 7 Cobwebs = 1 Silk at Loom | 35 Cobwebs = 5 Silk for a BedKill Black Recluses for bonus Cobwebs
Inside Spider Caves, Black Recluse spiders drop 2–5 Cobwebs when killed — significantly more than just collecting them from the floor. They are moderately dangerous enemies with a venomous attack that applies the Venom debuff (stronger than Poison), so bring an Antidote or Bezoar accessory if you have one. But the extra Cobweb drops from killing Recluses while collecting floor webs means you leave a Spider Cave with far more materials than from just walking through it.
🕷️ Black Recluses drop 2–5 Cobwebs each — kill them while farming the caveUse Silk to craft a Bed and other items
The Bed (15 Wood + 5 Silk at Sawmill) is the main reason most players farm Silk — it sets a custom spawn point. Beyond the Bed, Silk is used for many vanity clothing items (Tuxedo, Gi, Princess Dress), Silk Rope Coil (1 Silk = 10 Rope Coil), and various decorative items. Later in the game you will also use Silk for the Jungle Rose, the Gi martial arts outfit, and several Hardmode accessories. Always keep 10–20 Silk in reserve in a chest near your crafting area.
🛏️ Primary use: Bed (5 Silk + 15 Wood at Sawmill) for custom spawn pointPro Tips
Cobwebs also slow enemies that walk into them — placing Cobweb blocks in chokepoints near your base can slow enemies during invasion events, giving you more time to react.
The Bezoar accessory (dropped by Hornets in the Jungle) grants immunity to Poison, making Spider Cave exploration much safer since Black Recluses apply Venom on hit.
Cobwebs regenerate in Spider Caves over time — after a few in-game days the webs grow back, making each Spider Cave a renewable Cobweb source if you revisit it later.
You can also collect Cobwebs from abandoned underground houses and Dungeon corridors — while less dense than Spider Caves, these are useful incidental sources during normal exploration.
The Silk Rope Coil (1 Silk = 10 Rope Coil at Work Bench) is one of the most efficient sources of Rope in the game — if you need Rope for vertical exploration, converting extra Silk is much faster than buying it.
Silk is one of those resources in Terraria that players rarely think about until they need a Bed and suddenly realize they have to go find Cobwebs. The good news is that a single Spider Cave visit is almost always enough to get everything you need — 35 Cobwebs for the Bed plus extras for future projects. The Loom it requires also unlocks a large number of cosmetic and decorative recipes, making it a worthwhile crafting station to build early regardless of whether you immediately need Silk. Plan a dedicated Spider Cave run as part of your cavern exploration rather than as a separate trip and you will have all the Silk you need in minutes.
