I made a simple skimmer out of the spare liner I had in a corner of the pond. I fold my liner, not cut it.
Build a "small mini pond" about 1'x1'x2' that connects to your pond. Build up dirt around all the edges including the one between the pond. Go to Homedepot and get a plastic gutter drain spout to 4" connector. It has a 4" rectangle on one side and a 4" circle on the other, cost about 3$, this will be the water entry hole. Get a mesh laundry bag from The Dollar Store for 1$ to catch your leaves. Tie the bag to the round part of the entry piece. Now place it between the pond and the skimmer so that the water level is in the center of the rectangle portion. Try get get a tight seal between the liner and the piece. Place your pump or hose in the pit and let it run.
The pump is forced to empty the pit. Gravity pulls water and leaves in thew the gutter adapter. Leaves get caught in the bag etc. This works well for me. Since I use a bag and not a basket, every time that portion of the net is full, water forces the leaves to a new area of the bag. I can go a few weeks-month before I have to change if I need to. Works great for fall since it doesn't clog up fast.
Edit: Also made a great place for me to grow my duckweed and smaller lettuce/hyacinth since it gets good sun/nutrients and the fish can't get to them.
