Reminiscence of the Masskara Festival of Bacolod. For our project a smile for every page. The bookmark of smiles.
Picture
For this tutorial, we only need a cardboard size 2 inces by 4 inches.

Picture
Cut out the sides to create fuller edges.

Picture
Half inch from the bottom, cut straight then curve up half inch.

Picture
Half inch before the top, start cutting at a curve then stop. Do not cut all the way through.

Picture
Remove 1/3 of the middle piece as shown. What is left will become the smiley. Cut the mouth like shown.

Picture
Fold the middle piece to be able to cut triangles to where the eyes should be.

Picture
Your bookmark should look like this now when unfolded.

Picture
Letter O shown from this side. And the smiley is at the other side of the page in turn holding the page to prevent it from accidental removal.

Picture
Stress free warm smile every time you open your book.

Picture
Shown as a regular bookmark. With happiness inside.
