For the easiest variety of designs, I suggest you buy a clear case. If you are lucky as I was, you will get a clear case when you buy a phone.Basically, owning a clear phone case means owning an unlimited amount of phone case designs. You can draw some of those yourself or use cool pattern papers. Here I have some examples of those pattern paper ones.I also got a phone case which had a metallic look. And I really liked it but that lead it to be scratched to the point that I thought to throw it away. Obviously, I did not do that. I painted my own design on it with some cute strawberries. I used acrylic paint for this small painting. To protect it I used a clear nail polish. The case smelled pretty bad at first but after a couple of days, the smell disappeared. I am actually very impressed of how well this is holding on.If you have any ideas how to make your own phone case designs but with different methods then let me know. I like nice phone cases and especially if I can make them myself.
