When you like to read then chances are that you have quite a number of bookmarks. One tends to collect them. I have a fairly large collection, accumulated over a lifetime of reading.
Perhaps some of your bookmarks are just a scrap of paper. Or perhaps it is a receipt. Or it could be a piece of cardboard.
I like decorate my bookmarks. At least I use to. There use to be pieces of cardboard inside the boxes in which I bought my Earl Grey tea. They are just the right size for a bookmark. So I would collect them and then decorate them with abstract designs. In the figure below is one of favorites.
It has become a bit of a ritual to select a bookmark from my collection when I start reading a new book. However, lately I tend to select the same one over and over again.
