I have seen this stuff all over the internet, in craft stores, and I even own a few rolls. I didn't know what to really do with it until I saw Smash books, and started using them.
I have seen some tutorials on how to make your own. I loved this tutorial, here, so I basically did the same thing. I decided to make some to match my journal. This is my take on how to do it. SUPER EASY!
The other cool tutorials are everywhere, including here for a printable one that is genious.
Stay Crafty, My Friends!
