This is indeed cute. It looks like its just "done" versus a font....but who knows! Maybe someone will see it and clue us in!
I write in a font similar .. started doing it 10 years ago back in high school... on my notes that I passed along.
Remember how people put a "dot" or "bubble" where the lines in the letters ended/bent....? I just use a line above that mark and 3 dots.
Its just an own personal style.
Thanks ladies! Maybe it is just something that people like to do, I thought there might be a computer font or something. I'll just try to stick 3 little dots on and make it look pretty
