The book cover tutorial is as follows:
1, choose your favorite book cover. If it is a book of about 16K, you can cut the cover from the middle with a knife (be careful not to scratch it), and you can wrap two books; If it is a book of about 32K, you can cut the cover from the middle and then cut it, and you can wrap a small book in a quarter.
2. Press out the marks. Put the book in a proper position on the cover, center it up and down and to the right, so that both sides of the book can be wrapped in paper. Then press out the top, bottom, left and right marks of the book on the cover.
3. Cut "trapezoid". Take the book away and cut a trapezoid on the upper and lower sides of the seam. Be careful not to cut outside the edge line of the book, but outside the middle seam. Fold the two trapeziums after cutting.
4. Wrap the book tightly. Start putting the bag in. Put the book in the position corresponding to the trace, then fold it in the corresponding part according to the trace and wrap the cover of the book.
5. Fold the corner. In order to prevent the book cover from falling off easily, fold the four corners of the book cover in. The book cover is ready.
6. Compaction. After wrapping the book cover, you can find a thick book such as a dictionary to press the book to make it look neater. You can write the theme, name and so on on the cover of the book. If you want better protection, you can buy a transparent book cover in the stationery store and wrap it with another layer to increase the waterproof function.
