...err
We exchange bookmarks. We make them. We use slips of paper. If we dog-ear pages to mark our places, we definitely do not admit it. Finding bookmarks is never a problem.

When I worked in libraries we would come across all kinds of things used as bookmarks which were left in the books. I still have a lovely leather one with my initial embossed in it which sat unclaimed for the three months we gave before we owned them.
I heard that someone found a dry kipper bone frame but this could be a myth!

Rouan's and my mother used to use discarded computer punch cards from her office back in the day that they were a plentiful item. They were the best bookmarks I personally ever came across -- flexible, thin, large enough to stand out clearly from the pages.

I have a nice collection of interesting bookmarks, but I've stopped using them. I've become addicted to those colorful little sticky page markers (like post-it notes, but smaller and transparent, except for a colorful tip). They so conveniently mark exactly where you stopped reading, and they don't fall out or get in your way when you resume reading.

The one I like the best is one I got at a Drury Inn. I used it for a book mark in the inn and guess what it was still in the book when I got home. It is a TV information card that is laminated and just a bit longer than the book. I used to cut up Xmas cards and use them.

I'll make a confession: I always use bookmarks even though I don't really need them. My ability to find my place in a book without a bookmark has, on a couple of occasions, disappointed pranksters who have moved my bookmarks around. I just use bookmarks because I love to look at them.

Like Kathy, I also use sticky notes, mostly when I'm reading cookbooks and I want to remember to take a closer look at a recipe. I cut each down into smaller pieces, about the size of a matchstick, so I don't constantly have to buy new pads of them. Some of my cookbooks are bristling with these tiny bookmarks. It assures me that buying the cookbook was a good idea and gives me a good feeling even though I rarely cook anything from any of my vast collection of cookbooks.

Netla - Very impressive! (not needing a book mark)

And YES, the sticky tags are great for marking recipes. In books, I sometimes color code them - one color to mark words I want to look up, another for passages I may want to refer to at book club, and a third to mark my place. Hmmm ... sounds a bit OCD doesn't it?

Another one here addicted to sticky tags for almost EVERYTHING!

I use the library catalog cards that come with the MacNaughton rental books. My library no longer has a card catalog, so the stacks of catalog cards are used for notes, etc. I have a big stash at home and they are my favorite bookmark.

My favorite bookmarks are the return (round trip) train tickets from Gatwick Airport to Victoria Station in London. Not only are they slightly laminated so that they last a good while, but they are such wonderful souvenirs of trips to my favorite travel destination.
