I watched a planner video from this person:
https://www.youtube.com/user/jashiicorrin who uses washi tape paper to print her headers and stickers for her bullet journal.
I decided to try it for my October spread. Here is the washi paper I got:
washi sticker paper. I didn't want to get too much of it in case I didn't like it.
My theme for October is
Where the Wild Things Are. I found a font that looked similar to the title font from the book, and created this page with all the titles and headers I will need for October. The paper is quite transparent, and can be written on/colored on. Here is the page I made:

I created a 5mmx5mm grid that is 26 x 37 squares, which is the same size as the pages in my journal. This helped me know if the labels and stickers I made would fit correctly in my weekly layouts (I turned the layer with the grid off when I printed). I printed on the A4 paper, and then cut them out with scissors. Although I'm sure this could be done on a Cricuit or something.
Here is my spread. I experimented with coloring the labels, but I think I'll leave them transparent next time.

This is definitely a learning curve for me, but I'm pretty happy with the results so far.
Oh, and someone asked me last time how I determine what book to do what month - for October, I had to choose Max in his wolf costume!
