Dyed feathers are decorative items which have little use. They can be the colour of any dye, and are easily crafted. They can be added to a dyed (or plain) Leather Hat to make a colourful set of headgear, although it offers no protection.
The only way to obtain these items is to craft a normal feather or a swan feather with any dye. This means that a range of different colours are available for the player to wear. The recipe is shapeless.
The only current use of this item is that of decoration. They can be added to a Leather Hat of any colour, but beyond that they have no other use.
