Explainations and content of this datapack:

This datapack only add recipes and have no plan to use any kind of function.

For the stone of the piston you can use: cobblestone, cobbled_deepslate, blackstone or even end_stone. For the wool to string craft: any kind of wool work.

By the way every single recipes also work with the crafter.

If you have more ideas other craft let me know !
