Simple idea really.
On some servers you might be on a certain team. If your on a certain team, you'll probably want to...look like your team or have a feeling of "team pride" (or you probably just want to easlily be able to find other members of the team or maybe look cool or whatever...)
Anyways tabards would make it very easy to represent yourself to fellow server-goers. Here is how they would be crafted.
All tabards need 2 leather and 1 wool of any color.
This is how you craft a orange tabard...
and this is how you craft a brown tabard...
and a purple tabard.... I think you get the point. Tabards can be any color (as long as you have the dyes to make it that color of course.)
They can not be enchanted and do not give any perks (besides austhetics of course.)
They will have there own little slot beside ther armor slot and they do not stick to armor or anything so you can change tabards if you want to.
Once you make your tabard you will be able to choose a design for your tabard (for instance, maybe one design to choose from is a creepers head. If you choose it, a black outline of a creepers head will appear on the front or back of your tabard. I dunno how many designs the tabard creater would be able to choose from. 20 maybe? All having something to do with minecraft...)
If you want to change the design you have to go to a anvil and insert your tabard and some wool and you will be able to change the design.
You do not need armor on to have a tabard on.
Also should be available on survival mode, just in case you want to customize your looks.
