On my layout below, I used Upsy Daisy Designs papers, and on one of their pages, they had these cute small trees (you can see those small ones at the top of my layout). I wanted to duplicate the look of one of those trees, but much larger on my page.
First of all, I scanned in their small tree, and then used a "scan and trace" wizard in my Klic-N-Kut software so that I could cut out the tree. Then I scaled the tree as big as I needed it to be, and cut it out of a neutral cardstock. (The Klic-N-Kut is a die cutting machine that is plugged into your computer - FYI - it's not as well known as some others!) Then I duplicated one of the petals in my software and cut about three each from different cardstock that matched the Upsy Daisy papers. I then placed the tree, cutting part of one side off so that it would look the way I wanted it to on my layout. Then I added all of the other page elements. I think these papers are really beautiful for a nature-type layout (Upsy Daisy Designs - "A Walk in the Park").
