Having discovered that the latest book I got out from the library is a large hardback book I decided to move on from my pineapple bookmark that I have been using lately to one of my Celtic ones: the most popular one with the purple edging and pointy corners. With the pineapple bookmark the pages don’t quite lie flat where it is. But as I suspected with the Celtic one they gape rather more. Similarly with my latest version of the slip stitch one. Now with pointed corners! Even my plain Celtic cross lifts the pages a little more. Now with cord and tassel. And of course my latest Celtic cross bookmark. (Not yet with added cord) operates more like the other embellished Celtic ones.Just thought it was useful to give an idea of their relative thickness! Though when in use in the middle of the book they show slightly less!
