Here's another Die-Versions die card using the Tannenbaum die that I wanted to share with you and it's very different from the first one (which you can see here). It's an acetate card, which is easy to make but hard to photograph.
I used a mirrored cardstock that has more of a brushed finish as opposed to a shiny finish to cut out the image as well as the mat behind my sentiment. The sentiment, which I saved from a very old card kit, is on the front of the card and the tree is peeking behind it on the inside right panel. The little ornaments are some of the negative portions from when I cut the Tannenbaum die. I'm always trying to figure out ways to incorporate the negative pieces. :-) So when the card is closed, the tree looks like it's right behind the sentiment. When you open the card, you can see that it's actually on the right side. I mirrored the shape and matting on the inside left panel for a place to write your message (and to hide the adhesive).
Hope this gives you some more ideas on how to use these super fun dies! You can see this and lots more inspiration at the Die-Versions blog.
