1. Take a pink A4 cardboard and fold it in half along the center line to make a greeting card. Take another piece of purple A4 cardboard, cut it along the center line, leaving a part folded along the center line, and cut the folded part with a knife, leaving about 2cm when cutting.

2. Stick the left side of the greeting card with double-sided tape and stick the purple cardboard on the edge of the greeting card. Then the purple cardboard is wrapped into a cone from the upper and lower sides of the center line and bonded with glue stick.

3. Take a light purple square paper, fold the paper in half along the center line, then fold it in half along the center line and cut it into four small squares. Fold each square diagonally, then fold it twice along the center line, cut off four petals with different sizes, and open them to make four flowers with different sizes. Stick the flowers together from big to small in turn from the inside out, and then stick a pink button in the middle of the flowers.

Write happy birthday in the triangle gap of the greeting card with a rose pen, and then draw some dots around it with a purple pen. Such a beautiful birthday card is ready.
