Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: String has many uses in Survival mode – it can be used to make a bow, scaffolding, crossbow, fishing rod, lead, wool, or be used in a tripwire circuit. Although having no spiders makes it harder to acquire string, there are still many ways to get some. String can be obtained by breaking cobwebs with a sword. In Bedrock Edition, cobwebs can also be crafted to produce 9 strings, so that would make it better to break cobweb using shears. if you have a mineshaft, stronghold library, zombie village, or woodland mansion with a spawner room near spawn, this would probably be the easiest way to acquire string. String can also be gifted by a cat, and is dropped by them upon death. You can also obtain string from bartering with piglins and killing striders.
