Leaf vein bookmarks can use osmanthus leaves, heather leaves, papaya leaves, tea leaves, magnolia leaves, etc. Leaves of evergreen woody plants are suitable. Leaf vein bookmarks are made by removing all the epidermis and mesophyll tissue of the leaves, leaving only the veins. You need to choose leaves with flexible texture, and be careful not to damage the veins when washing.
How to make leaf vein bookmarks
The time to make leaf vein bookmarks is in late summer or autumn when the leaves are fully mature and start to age. Select suitable leaves and put them in 10% hydrogen oxidation temperature. Boil the leaves in the sodium solution and gently flip them with a glass rod or tweezers to prevent the leaves from overlapping and allow them to heat evenly. Pay attention to safety when using sodium hydroxide and do not hold it with your hands.
Wash the cooked leaves with clean water, lay the leaves flat on a piece of glass, and use a small test tube brush or an old toothbrush with soft bristles to gently brush away the rotten parts on both sides of the leaves in the direction of the veins. The mesophyll of the leaves is then soaked in hydrogen peroxide for 24 hours to bleach, and finally dried.
