The paper clips probably will not harm the anything, but is an inefficient way to hold Riccia down.
Go to the pharmacy and pick up a package of small, fine hair nets. Clear is a good color to buy. They will have an elastic opening on one side.
Take an object(a flat rock or similar), the size of the Riccia 'patch' you want to cultivate on the substrate, and lay a 1/2" - 3/4" bunch of Riccia over the object.
Now take the hair net and put it over the object and Riccia with the elastic on the bottom. To make it stronger, tie off the bottom(elastic) with fishing line as tightly as possible. Now, take some more fishing line and wrap the whole thing as tightly as you can make it to hold the plants and netting down securely.
Riccia wants to float and unless really tied tightly, will hover over the object if not tied down tight. You will not hurt the plants by making it tight.
The plants will grow through the netting (especially well with good light) and hide it in a short period of time, and you won't even know it's there. CO2 helps the growth as well.
From there, all it will need is a periodic 'haircut' with scissors(careful not to cut the netting) to keep it short, and to look nice and uniform. Don't let it get much longer than 1/2" above the netting or the bottom plants will start to die off.
