Have you got some paper, a pair of scissors and, above all, a desire to decorate your house? Then, we have the perfect holiday artwork for you: Make Star Wars snowflakes (雪花). Remembered as a cherished form of work in classrooms before the holidays, paper snowflakes have drawn many people's attention again.
The designer, Anthony Herrera, just recently released his 2013 collection. "The Star Wars snowflake designs began as just doing designs of characters that I and my daughter wanted to make three years ago," Herrera told us in an email. "The second year I introduced vehicles, and this year I decided to push further by designing battle scenes."
Sometimes, he feels a bit bored with his job. With each year, the designs have got more detailed and various, but the process of creating them remained the same: sketching figures on paper with a pencil until a symmetrical (对称）pattern comes out, then scanning the designs and cut them with scissors. However, he says he has plenty of ideas for new flakes next year, so no two will ever be the same. Hopefully with Star Wars: Episode VII coming in 2015 he'll have even more work in the future.
Check out your favorite finished versions of Herrera’s flakes (from both 2013 and previous years) and download the pictures beneath them and then get down to creating your own work. A warning: Most designs aren't for the casual flake-maker, so patience you must have.
