You can see a tutorial on how to diecut washi on the LMT blog.
Another paper challenge was to use scraps to make a chevron. Instead of doing a horizontal chevron, I just did one vertical chevron going the length of the page. And, of course, I made a card as well.
I made this simple card using PWP stamps. I stamped the background by just repeating one stamp over and over. I love the fun pattern it creates.
