Crafting

In order to craft hanging lights you first must craft the lights. Lights come in many variants, fairy light, heart light, moon light, star light, paper lantern, orb lantern, flower light, candle lantern, oil lantern, snowflake light, icicle lights, and meteor light. There are also spooky lights, spider light, ghost light, jack o'lantern, skull light, witch light.

Fairy lights are crafted by a horizontal combination of iron ingot, string or stick, iron ingot, along with any combination of lights to specify a pattern (left-right, top-down). If glowstone is included the hanging lights will twinkle. If string is used there will be slack in the connection and if a stick is used the connection will be straight. The hanging lights item will only show the first four light colors, but the most lights that can be crafted is eight by placing a hanging lights in a crafting table with eight lights.

Here are the light recipes where the red dye in the recipes can be any dye.
