Has anyone else noticed their handwriting varie depending on what kind of writing instrument is implemented?

This should probably be in IMHO.
As for the question, sure. My handwriting actually varies widely depending on my mood too. I’d guess that it probably has something to do with the tension in my hand and the writing pressure. Likely the same things that influence writing with thicker/thinner/greasier/more brittle/etc. implements.

How much coffee I’ve had (too little or too much) can also be a factor.
