This is a shark bookmark, designed so you can see the fins of the shark above the book!

The top half is deliberately bigger than the lower half so it is more realistic and looks more aesthetically pleasing.

The lower half is thin so it fits between the pages of the book comfortably.

The two parts do need to be glued together so that they are stable when the bookmark is in use. Please DO NOT put the bookmark in your book until the glue is dry! I had to learn this the hard way!

PLEASE consider boosting this model as it helps me to be able to make more models like these! It's also excellent feedback!
