Methods/steps:
1. First, fold A4 paper in half, and then draw your favorite milk tea pattern on the paper. Both sides of the pattern can be the same or different. Pay attention to the pattern of milk tea must be the same size.
2. Then cut out the drawn pattern with scissors. When cutting, leave appropriate blanks on both sides and bottom of the pattern.
3. After the pattern is cut, the blank parts on both sides are folded inward a little, and the bottom is also folded inward.
4. Finally, glue is coated on the blank folded at both sides and at the bottom, and the two painted patterns of milk tea are aligned and bonded. When the glue dries, such a simple blind bag of milk tea will be ready.
