Here is a Christmas tree that I made for a card one year.
Here is a close up in case you need help.
Yip, you got it, it is made out of pencil shavings. You need some good strong glue, preferably quick drying but otherwise it is reasonably easy to do. I helped the children at church ages 3 to 12 to make pencils shaving Christmas trees for calenders one year and all managed very well.
