decoden question?

[microbial]

ahh, I hope i'm posting this in the right area? >< I really have no clue where else to ask... o_______o;

Well, basically, I did decoden on my phone, but I have absolutely no clue what kind of case to put it in now. .___.; I used mostly half-pearls, 3D-type roses & those little crystal thingies. So far it seems pretty sturdy, but I'm still a bit worried that a case would cause pieces to fall off, & I really don't wanna wreck it u__u;
Any suggestions or tips would be really wonderful!
