Here are some free calendars that I especially loved this year (but didn't print):
Geometric with large poster capabilities! (It also comes in black and white.)
This is my favourite one!
I really like the formatting on these. That's something I might attempt next year.
These are too cute! (But I think I would've been tempted by sweets all year!)
I also really liked Scout Creative's free printable calendar this month and did print that one (resized as a mini calendar instead). They've switched from 3D calendars (you print, cut out, fold, glue, and display equaling too much work) and moved to desktop calendars with a free printable card calendar. I was so over the 3D printables they were sending out every month last year, I didn't even consider printing a single one. So, obviously, I'm really happy they changed their format!
