As of now the Papercraft armoury only uses items that existed in old Minecraft and doesn't have any of the modern-day textures or items that made modern Minecraft the great, jam-packed game it is today.

It would be really cool if some of the main items such as tools, weapons, armour, food and utilities were added to Papercraft with new textures while the old ones would be there for your convenience. In the case of armour, being able to apply that armour to your papercraft warrior would allow more possibilities for them.

The papercraft system could definitely use some improvements, I will make multiple tickets to make it easier for the devs to list them off one by one.
