This is something I feel kids will find difficult. I had to trace the cut pieces on several folded areas to get the shape cut nicely. And you use an exacto knife, much easier then tiny scissors. It took at least one practice snowflake for me to get one looking nice. But it sure is fun and they are very large, they fit a 11 x 8" paper. You can print the pdf to cut from if you follow the link in the website listed. Have fun, be sure to decorate those droids nice!
