If you've got some popsicle sticks or tongue depressors, a hot glue gun, and a sprig of evergreen, then you've got yourself a good ol' Charlie Brown Christmas tree.
1. Simply put your popsicle sticks or tongue depressors in an "X" shape and dab some hot glue in the center between them to make the tree base.
2. You can take a smaller popsicle stick and break them into three small pieces (using only about 1/2 the stick). I dabbed a generous amount of glue on top of the base in the center of the "X", put the bottom of the evergreen sprig into the glue, and then used the 3 smaller broken-off pieces of popsicle stick to form a triangular base around the glue.
The good thing is is that the tree is supposed to be imperfect and lopsided, so perfection is not necessary.
3. If you have some blue fabric or scrap fabric (I used some from an old t-shirt), you can wrap it around the base like Linus' blanket (not necessary though).
4. Place a single small ornament on the twig and let it droop. :) I lucked out with a couple of sets of mini glass ornaments. They were originally marked at $8.00/set at Urban Outfitters a couple of years ago, but I bought them in January well after Christmas and got them for $0.50/each. If you don't have small enough ornaments, you can always improvise and make one out of a red pom pom, felt balls, or anything you can find around your house. Or, if you have a long enough piece of evergreen, a regular-sized ornament may work, as well.
It's a great little decoration for a kitchen window sill or desk at work.
