1. Preparation materials: scissors (used for cutting white cardboard), thick white cardboard (used for making bookmarks), brush (used for coloring bookmarks), ribbon (used for tying bookmarks to increase aesthetics), water, carmine and deep ochre pigment, etc.
2. Cut the cardboard: Cut the white cardboard into strips with scissors, and pay attention to the width, not too wide or too narrow.
3. Coloring: Use a brush to soak the white cardboard with water, and then use a brush to gently coat it with rouge red pigment. By clicking, pressing, wiping and other different strokes with a brush, you can smudge the flower tree and increase the aesthetic feeling.
4. Draw trunks and branches: Draw trunks and branches of flower trees with dark ochre pigments. Note that some branches are hidden by flowers and can't be drawn.
5. Tie the ribbon: use a utility knife to carve a small gap at the top of the bookmark, put the ribbon in and tie the knot.
The above is how to make bookmarks of Ai Qing's poems. I hope these steps can help you complete a beautiful bookmark.
