Corrugation Fascination

Have you played with the variety of corrugators on the market? I have a Marvy/Uchida wavy one that I got from Paper Wishes. At the time, I purchased it because I thought it would make a neat textured background for a card focal, and because it would be helpful for making "envelope cards". I have used it for both of these things, as you can see in these pictures. 

















 
However, I had not considered using it on a scrapbook layout until recently.  Here's a fun one where the small corrugated strip reinforces the stripes in the background paper.
