For people who don't want to carry around a discbound notebook or just don't need all the extras, I've scaled my Spood Planner down to just the basic spider information pages. This A5 book is printed on 80lb paper so is pen-friendly. There's enough room to document and track 18 spiders (book is 36 pages). This size also fits in A5 covers and A5 traveler's notebooks if that's your thing too! :)
 
I chose to leave the pages as minimal as possible to give more freedom to track what matters the most to you - nothing is worse than a notebook full of sections you don't use! Let me know if you need any ideas, but there's plenty of space to track molts, pairings, instars, sacs, etc! 
 
EXTRAS:
- Canva template to easily print pictures of your spiders to fit the pages
- random stickers and other silly things from me. :)
