how make particle in front of GUI.Label

i have one label and than
i want the particle in front of GUI Label
How???

Put the particle on a other layer and set a second camera on this layer only.
Then put the 2. camera in front of the first cam in depth order of the camera the main camera.
Make the 2. camera a child of the fist camera.
