In this first layout, I used washi to create a border around the entire layout. The yellow looks great against the white/patterned type background and helps to bring in the focus onto the photos and journaling box. It's a bit harder to see against the yellow background, but I used the same washi on that journaling box, too.
In my next layout, washi makes an even bigger impact by using coordinating patterns to make my own background sheet. I started with a neutral grey background approximately 8x10 and after choosing my washi, began laying it down in straight rows. I simply ripped, rather than cut straight, the ends. It was a super quick process and brings a lot of interest to the page. I also added a torn strip of washi across the upper left of the page. It helps to balance out the title and sticker cluster at the bottom right.
