WARNING: my handwriting is horrendous!
Current Grocery list
To do list
Recipes I find on the internet
Price list(I'm currently making up a separate price chart on the computer so I write stuff down as I come across them in the store)
Library list on books to check out/recheck
I also write down appointments(usually with weekly to do), bills, and even a list for the order I need to read my library books!
It's not fancy but seems to work for me!
