Hang them on a chain? XD
IDK it doesn't look too crowded to me

Did u buy them? Can't be used as a necklace? if yes then use the same concept and hang them up, if not use magnetos or something like that...

OH MY GOD YOU'RE ALIVE!

So pretty~~ this'll do well as a wall ornament.

That picture is soooo precious omg ;;

Make like a wall art from them maybe like make your won 3D poster if you get me??

If you move the flower and the rock near the middle, you can spread the symbols out in one horizontal line. That may help if you think it's too crowded.
I personally think it's fine, but that's just from the picture.

It does look a little crowded...
Maybe just display a few of your favorite symbols?
Like your favorite EXO member's symbol or something
idk it's your place

Switch the wooden tray for the photo frames place.
But keep the red/pink flower in its place. Them spread the symbols in across the table.
In order of shape: teleportation, Light, water, healing,strength,lightning, wind, frost, telekinesis, flight, time control, then fire.
Personal preference:xuimin,Tao, lay ,Chen,kris then luhan.. Followed across on the other side spread apart d.o Kai, Baekhyun sehun chanyeol then Suho

idk but it kinda looks alittle crowed -shrugs-

You could tie them with a nice braided string and then - once they all have a piece of string - tie them together and display it like a dream catcher or something?? I dunno, it looks alright on your table but they're such pretty symbols, you could do so much with them!

I think it looks perfectly fine! Its super cute, I love it ^_^
