If you feel more comfortable doing it with the other hand. that's fine. Just reverse the side that I said and do the things mentioned. If you do want to learn to net right handed, you can practice those techniques in the yard and try putting them into practice when you;re on the water. It will feel a little more comfortable each time that you do it. It sounds like you need to build up the muscles on that side by just practicing with a little weight in the net.
