Hello!!! This isn't literally my blood ya' know... I was just bored in my classroom so I started to draw triangles, and I needed something to fill them in, so, why not the countries where my blood is from? Scotland, Holland, England (I know that is the UK flag, but I just didn't wanted the red&white flag) and on top (of the world) Venezuela, where my parents and I were born.
There are many other flags but these are like the principal.
