Materials: cardboard of various colors, colored pens, pencils, scissors, eraser, and film.

1. Find cardboard with the color you like. This determines the overall style of the bookmark, and then draw the length of the bookmark on the paper.

2. Use scissors to cut out the painted bookmark. When cutting, cut neatly along the line; this step is to test everyone's hand-drawing skills. Draw the pattern you like, it doesn't have to be too complicated. If you have no foundation in hand drawing, you can also write a self-encouragement motto.

3. After drawing, you need to use colored pens to color. The color can depend on personal preference or you can find relevant material templates for coloring.

4. Find some plastic film or plastic wrap, or cut it off from a plastic bag.

5. Cover the bookmark with film, and this handmade DIY personalized bookmark will be made by you. If you want to make it more convenient, you can make a small hole on the head of the bookmark and tie a string on it.

6. A set of personalized bookmarks in your own style is now complete.

----------

The production method is as follows:

1. First, prepare the materials. The materials can be drawn by yourself. Here we first draw by hand, on white cardboard (since there is no white cardboard, we use white paper instead) and then use pencil to draw the prototype of the cardboard bookmark.

2. Because pencils are easy to erase, use a pen or watercolor pen to color the cardboard bookmarks and then use an eraser to erase the pencil scratches. Since this is a simple explanation, there is no demonstration here.

3. Cut out the cardboard bookmarks with a paper cutter or scissors.

It’s basically completed (what you’re doing here is a prototype, and you’ll have to rely on your own creativity)
