That is neat Mac. For some reason I thought these were an accident or is that tape?
Like the rest of you, I have used them in books and such to mark something. You should see a cookbook I have that has a ton of them marking recipes that "one day" I plan to make. I really like all the new stuff they have come out with. Dh has a highlighter that has stickies so you can do both at the same time. I have bought tabs but haven't used them yet.
Anita, I am with you that tape is more secure. I recently bought Super Sticky Post-it notes that really do stick. That is what I need to be using. I would not use them in a book because I feel they are a tad too strong and might tear a page.
