I made these stuff a couple weeks ago, when some ribbons in my storage fell from their box. Then I had to organized them again. And I tried this idea
1. I used two WRP boxes, and some doubletape for the material. and for the tools, I used a CD for making the circle, and scissors for cutting the paper
2. Make two circle from the boxes
3. Make a hole in the centre of the circle, then cut the inner circle to the inner marking line, then fold the paper that you have cut.
4. Make a roll of paper from the scrap paper for the core, it's height is little higher than the ribbon. use double tape to stick the core and the covers.
5. Then roll the ribbon
6. It's done
