Elements vs Photoshop advice please

Hello, I wonder if anyone can advise me please. I am trying to learn how to make repeat patterns for textiles from photographed handpainted designs. I struggle with photoshop because it's so complicated and I am fairly new to it. I have had more success using Elements for editing photos - which I currently have on free trial. However, I cant figure out on either program, how to make repeat patterns from photos. I dont have a lot of time left on the free trial or time to dedicate to experimenting before it runs out. Can anyone advise me whether it is possible to do this on Elements please - if so, I will buy it and figure it out later. If not, I will have to stick with Photoshop and continue to be overwhelmed by it I suppose. Many thanks if anyone can help.
