You'll use one toilet paper roll per favor. Measure the scrapbook paper to fit the roll and cut with scissors.
Add a layer of Mod Podge to the toilet paper roll and to the back of the scrapbook paper. Wrap the paper around the roll, making sure to smooth out any bubbles.
Let dry 20 minutes. Bend the tops over by folding the toilet paper roll in half and then pushing two thumbs together. Do at one end.
Add goodies inside the favor and fold the other end together.
Finish by adding decorative ribbon as shown. I used a little Mod Podge on the back of the ribbon to keep in place.

Notes
If you find the scrapbook paper to be wrinkly when dry, you can paint a layer of Mod Podge over the top and it should un-wrinkle.
