1. materials: prepare the materials used before construction. First, it is square colored paper, preferably double-sided colored paper. Then there are scissors, pencils and rulers that we often use for manual work.

2. Fold the paper: put the colored paper on the table and choose a color as the background color of the bookmark. Use a ruler and pencil to measure a square, each side is about 6-8 cm long, and then cut it with scissors.

3. Folding into a triangle: Fold one corner of the square paper into another corner to form a triangle. Hold down the bottom of the triangle and fold diagonally to form a smaller triangle again.

4. Fold into the shape of love: Make sure the tip of the triangle points to you, and then fold the left corner to the right to form a small triangle. Fold the left corner to the right again, but only a small part this time. Repeat the same folding step until you leave a small tail at the bottom. Fold the tail at the bottom and stuff it into the bottom of the paper block.

5. Bookmark: Open the paper heart and you will see a beautiful shape of love. If you use double-sided colored paper, make sure that the colors and patterns are visible. You can trim the edges with scissors to make the bookmarks more tidy.

Function of bookmark

1, marking the reading position: the most common function is to mark the last reading position. When you close a book or magazine, bookmarks can accurately indicate where to continue reading next time, so you don't have to rummage through everything.

2. Protect the pages: Bookmarks can prevent the pages from being folded or worn, especially in hardcover books or important documents. By inserting bookmarks, page damage can be avoided and book quality can be maintained.

3. Personalization and reminder: Bookmarks can be used to personalize your reading materials. They can be decorations of various designs, colors and patterns, reflecting your interests, preferences or styles. Bookmarks can also be used to remind you of specific information about books or materials, such as the title, author, important page numbers or reading goals. This is very useful for study and research.

4. Gifts and giveaways and important tools: Bookmarks are a common gift and can be given to friends, family or colleagues. They are practical gifts and usually have aesthetic appeal. Bookmarks are small but important tools in reading experience, which can facilitate us to manage and enjoy books and other reading materials in different occasions.
