The mesh is cut to 2 times the size of the tank that you want the moss wall to be in. You would need to fold the mesh in half and stuff the moss in-between. Cut some holes on the perimeter of the mesh so as to stick in the suction cups.
For my demonstration, it's for a small 1 ft tank, hence one suction cup is sufficient. If you are doing a large wall, you will need to put in more suction cups especially on the 4 corners, and also some suction cups around the centre of the mesh to prevent warping when the mesh is in the tank.

Fold back the other half of the mesh, and tie up the 2 halves together. I'm using some tying wire here, since it's simple and I have it available on hand. You could also use fishing line or nylon thread to tie it up. Do not use any cotton thread since it will disintegrate after a short while in the tank. Remember to insert in the suction cups.
The above diagrams illustrate the final product.

The final step, wait for the moss to grow out of the mesh, and thou shall be rewarded.
Growing aquatic moss in the aquarium is not very difficult. Aquatic mosses can be considered to be the easiest aquatic plants to grow in the tank. In general, if you can keep Java Fern alive, you should have no problem keeping Java Moss and most of the aquatic moss. Most of the moss are not very demanding in their requirements. They can tolerate lower light levels than the higher plants, and they can grow well even without the supplement of Carbon Dioxide to the aquarium. They can also grow with minimum nutrients. However, with proper lightings (about 2 watt/gallon), CO2 supplement, and some macro-nurtients and micro-nutrients, one would really be able to see the true beauty of these aquatic moss wall in the aquarium.
