When I was young I thought for a bit about the anatomy of the bag me and my parents carried laundry in to the laundromat.
I decided to place the whole bag in the machine with the opening of the bag forwards; open position and then pull the ends of the bag toward me. [Pulling the tips of the outer side of the bag with one hand while pushing the clothing inward.]
It's an easier way to do your laundry because you don't need to hold something heavy with one hand while placing individual clothes inside the machine. You can place all of them with one movement.
I really don't know how far this post will go. It works for most types of clothes unless you have a thick carpet inside or something like that.
Apologies for my horrible drawing skills. They will improve with time.
