Sacks

Sacks would be a bundle, but it comes with stuff in it. The stuff in it could have armor trims, music discs and etc. Sacks would be useful for carrying food. It could be able to be placed in the offhand in bedrock edition. (Because Java Edition could already). They would be shown to behind the player on their backs. It would be 3d also. It wouldn't be a flat picture. Other players could see it. Sacks can have designs on it, but you would have to find fabric pieces with designs. You can also decorate them with a loom.
