Most fish landing nets are too coarse and damage fish. I use an opened wire coat hanger, some clothes pegs and a suitable sized heavy duty plastic bag. Once the fish is in, unpeg and remove as much water as you can. If its a LARGE fish/bag, you may need a landing net there to lift out. I find a clear plastic bag is easier to trick fish into than a pillowcase.
I always just cut up a t-shirt and kinda wrap it in the t and just pick it up. Seems to do little to no damage to the fish so I would say its a good option. I have done it many times.
