Red envelope, red packet or 'hongbao' is a monetary gift which is given during Chinese Lunar New Year or other special occasions such as weddings, the birthdays or graduation.
Traditionally the 'red' envelope comes in red which symbolizes good luck with gold print or hot stamping of auspicious greetings. Today, besides red, we see them in gold, pink, orange, yellow & hues close to red.
Recently, a friend gave me a set of creatively designed red envelopes which she received from a printing company. It came in multiple colors including an unusual teal.
Each envelope are conceptually designed with spring couplets (duilian) in balanced four characters for the Chinese Zodiac year of sheep.
Too bad I can't do a good translation on them. And seriously please do not try to Google translate these couplets as it would distort the meaning and turn them into jokes.
I find the glue-less concept with just a die cut slit is brilliant idea for the closing the envelope. Just a piece of square paper with few folds, it is transformed into an envelope.
This is a good idea for other stationery and gift packaging designs besides red envelope.
