I started making these trees and Russell said that I should make little snowmen to go with them. Yes! Then he said that it's ironic that we make paper out of trees, and now I was trying to make it back into trees. Yes again - but not as helpful, focus Russell. We figured out how to make these cute little snowmen cutting out three of the snowmen pattern below on a fold with white cardstock, and taping them together by their folded centers. It's so easy and they turned out great.
The instructions for these trees are found here. Some tips I found out is that it's much easier to make them out of paper than cardstock, or construction paper. Paper makes cleaner lines, folds much easier, and keeps its shape better. The big light green ones were made with construction paper that we had in our primary cabinet, and the folds didn't hold as well. It kinda makes them look like fatter trees, which is fine, but the fatter they are, the easier they topple. You could also try cutting them out of wrapping paper if you have it or wanted to do some cool patterns.
Here's what the trees are doing now - decorating our office.
If you want to make them too here's a pattern that I made to make it easier to cut out the circles etc. Print on an 8 1/2 x 11. The smaller set of circles is for one smaller tree out of 8 1/2 x 11 paper. The larger circles is for the larger trees to be cut out of 12x18 paper.
