Bard is a immersive plugin that allows you to play instruments when holding them. Together with the Vardenfall texture pack and optifine they are 3d Models that can be held and worn on the back I have created.

I will keep learning and develop it further.
It is possible to support me by donating to help me spend more time on it
Thank you
