Aight, so here are a few templates for themes:

And yes, there are many because I was bored skskksks

Border samples: (they're mostly the same photo cuz I was too lazy to search for some good photos lol)

•#1 - Simple border, 1 thin layer
•#2 - Double colored border, horizontal layers.
•#3 - Double colored borders, vertical layers

•#4 - Dual slanting borders
•#5 - Single, thick border
•#6 - 4 colored border, colors can be repeated.

•#7 - 3 layers of border, innermost one will be the most transparent
•#8 - Design border
•#9 - 4 layers of border, similar to #7

•#10 - 3 thick borders
•#11 - Highly edited bg
•#12 - Dual colors, but nothing separating the colors

(Yes, I suck at coming up with descriptions)

Okay, so something that I have noticed is that different people like different sizes for their headers. So, I'm giving you a choice. You can chose a rectangular one, or a square one. The examples give below are square, but it would be the same for the rectangle ones too!

Header samples:
