Here's a montage of my process in figuring out a nice signable logo/sigil. I got married to my husband 3 years ago and hadn't stopped signing my work with my maiden name or plain print initials. It struck me a kind of stupid, since my work isn't well known enough for me to cling to a name I've always found awkward to sign.
So I started doodling. I went through more literal letterforms with accent strokes, realized it felt too fluffy to do that, I wanted something easier, more efficient than what I'd been working with before. I didn't want clunky, forced and stylized, I wanted clean and simple. I played with combining letter forms into a little picture, and the five-stroke owl emerged.
I can even have him "stand" on the date, if I choose. And, it was a simple jump from the pen-stroke owl to a more formal version I can use for vector graphics if I want to sign those.
So, there's my owl.
