There have been lots of comments on the pop up tree on JustCards so I am reposting the links for a video about assembling the tree and another site with inspiration.
Here is the link to the video on making the pop up Christmas tree. http://melanieschulenberg.blogspot.com/2009/09/o-christmas-tree-pop-up-tutorial.html
Here is a link to someone else who did some cool things with the tree: http://www.blogger.com/goog_355538798
And here is the offer. I will send the parts for a pop up tree to the first 10 people who leave comments here that they would like to have a tree. It will just be the parts needed. No decorations. You can ask for a green or white tree. Your choice. Please leave an email address for me to contact you for an address unless you are in the contact list on JustCards.
