Boek met beschermende omslag
How to do it
Open up the book and adjust the sticky back plastic, so that it is 2 cm bigger all the way around the book (for folding inside the cover). Slowly pull off the protective paper and attach the self-adhesive sticky back plastic to the book.
Use a ruler to smooth out air bubbles.
Cut off all four corners of the sticky back plastic at an angle. Make an incision on each side of the book's spine (at the top and the bottom), creating a flap.
Fold the sticky back plastic and attach it onto the inside of the book cover's front and back. See the photo.
At the top and bottom of the spine cut off the flap approx. 5mm from the edge of the spine. Tuck the small flap inside. You may use a knife for tucking it inside.
