This is a project that I made many years ago but it is a really fun 8x8 handmade planner.
I used the Preservation Series 8x8 Scrapbook by SEI for my base and then lots of cardstock, printable calendars, etc.
You use the page protectors to create pockets to store cards, etc and then there are inserts made from cardstock that have a calendar, birthday list, etc. I like this so much I might have to re-do it for this year. I love a write-in planner, I am not much for keeping everything on my phone/ipad/computer.
The video shows off the details and there are some instructions to create this fun project.
