I've found myself shifting planning styles over the past year, and wanted to experiment again with using a print planner and a new layout. I'm really excited about the twinbook. First, the cover is gorgeous and it's a treat using something so nice. Second, I like that I can pick different books, both dated and undated, to meet my needs. I started with the 2026 monthly planner refill and the weekly undated horizontal. It's great so far and I'm glad to know that if my needs change again, I have other options available and can keep using this beautiful cover. Works great with my pens and mildliners too!
