Writing with a thick pen
Most of the time these days I use a finer nibbed pen. But I also have some broader nibs inked up.
Most of the time I use the broader ones to draw divider lines between sections in my Hobonichi Techo Cousin A5 planner. But sometimes I take one up one (or one of the numerous broader nibs than I prefer gel ink pens I have laying around after testing things out or from my former life as a borader nibbed person) and start writing with it.
And it looks so strange to see these thick lines when you’are used to like a EF nib or a ~0.3mm gel ink pen.
