I usually design anything on photoshop during my free time. It's just simple things I do that don't really require any design skills. I made a calendar recently for writing down my first semester of university. I didn't want to buy a calendar type book so I thought I can just make the template and print it whenever I need it.
The first design, I made it portrait.
But then my sister told me that it'll be difficult to write anything in those boxes cos it's too small. So I changed the template to be landscape. I continue making the template from September to December.
If you guys happen to like it, feel free to tell me, I'll send the file.
