The point of this post is to gather and suggest new designs for decals from the community, working in the same way as post #276 [New Poses]. So stuff like ovals and equilateral triangles or you could design something a post it here such as symbols, names, words etc.
Feel free to post your ideas and designs for decals!
since the majority of the above are elemental decals I’m going to link my elemental decal suggestion here
