I went to the beach today - I have added a little pattern that is supposed to represent the little depressions that water makes in sand. Googling pictures tells me it's called rills. and a Padres colored version.
This is something I want to get better at, background patterns. I think it really improves this one. it also took like 1 minute, it's some wavy lines at 50% opacity

I use the majority of the logos from this thread in my league too, and I still have all the files, so they'll still keep getting updated when I have an idea - actually this one will likely be further slightly improved if I can figure out how to stuff a baseball theme or "baseball club" on it lol
*I will get to the new list too!
