Take a piece of stiff cardboard, draw the shape of a letter onto it and cut it out. Draw around it to make a second letter shape. Cut it out.
Cover the front of your cardboard letters with old wrapping paper. Label each edge with a letter. For example: A, B, C etc.
Take a long strip of card (about 6cm in width), lay the letter against it and mark it with the start and end position of each edge and the edge’s name (A, B, etc.).
Cover the reverse side of the strip with the wrapping paper. As you trim it, leave a 2cm border of paper all the way around. Cut triangles into the border at each of the mark points to create tabs. This will make your letter easier to stick together.
Using glue or double sided tape, wrap the strip around one of your cardboard letters, matching edges A together, then B and so on. The sides and back of your bookend are now finished.
Place some stones in a plastic bag and knot the end. Put this into the base of your bookend (this will weight it down) and stick the remaining cardboard letter over the front.
You’ll need to make two bookends for your bookshelf. Try experimenting with different wrapping paper to make to give each one a unique look.
