I have designed a red envelope for the Chinese Year of the Dragon, suitable for holding 10 banknotes with a face value of 100 yuan each. If you wish to include more or fewer bills, you can adjust the thickness of the gold border. I have incorporated an opening at the top of the red envelope for easy removal of banknotes, and you also have the option to remove this opening for a better seal of the coins inside the envelope.

I use double-sided tape to adhere the upper and lower parts of the red envelope. It's a good idea to trim the excess parts with a craft knife after attaching the double-sided tape to one side.

我设计了一个适用于存放10张100元面值人民币的中国龙年红包。如果您希望放入更多或更少数量的钱币，您可以调整金边的厚度。我在红包的顶部设计了一个开口，方便取出纸币，您还可以选择去除这个开口，以便更好地密封红包内的钱币。

我使用双面胶来粘合红包的上下两个部分。双面胶贴合一边后使用美工刀裁去多余部分是不错的办法。
