I love distressing on my cards and pages. I feel it just gives that extra "something". Tim Holtz is the King of Distressing and really made it a huge part of scrapbooking and cardmaking. He has some great products out that make distressing so easy.
The Paper Distresser is one of my favorite items. I used to try to use open scissors, my X-acto knife, you name it. This tool is the easiest by far. And now we carry it!
If you would like to see Tim using the Distresser, check out his blog. Right now he is making tags for his "12 tags of Christmas", one each day for the first dozen days in December. They are really stunning and you should check them out!
