There are many things you can create from ribbon rolls. Why not use them to create your own unique ribbon jewelry. Here are a few ideas:
Beaded Necklaces: This ribbon jewelry project is super easy. Choose your favorite ribbon and measure it by looping it around your neck. Make it as long as you would like, add a couple inches for the knotting, and trim the piece off the ribbon roll. Then, simply add beads! There are many kinds of beads that can be used on this project; and thousands of colors. Thread a bead onto the ribbon and move to the center. Tie a knot on each side of the bead making it immobile. Continue to do this until you have the desired look. This example has extra ribbon cut to make two cute bows at the end of the beading. Simply finish the necklace by tying the ends together in a bow.
Metal Tab Ribbon Jewelry: 
For a bracelet, thread your ribbon through a washer, making sure to leave plenty of ribbon left over on the end. Thread the ribbon through a second washer and then back down through the hole of the first washer. Pull the ribbon tight. Thread the ribbon back through the hole in the second washer. Thread the ribbon through the middle of a third washer and back through the hole in the second washer, pulling the ribbon tight. Repeat this process as many times as you like until you are happy with the amount of washers on your necklace or bracelet. When you are done, trim the ends of the ribbon so they are the same length and tie them together.
These pop tab necklaces can be done with several ribbon colors. For this example, there are two colors. Start by measuring out the two ribbon rolls to the desired length and knot them at one end. Using an under and over weaving pattern, add the first tab to the bracelet by weaving the ribbon under the first slot in each pop tab for each ribbon. Then add the second pop tab by weaving over the first slot. Follow this with weaving them back through the first pop tab. Tighten the ribbons to make sure they are laying correctly and add the third tab using the same steps. Repeat this pattern until your bracelet is the desired length. Once done, simply tie the ends together into a bow.
Ribbon Headbands: While not exactly ribbon jewelry, the only materials needed for this easy craft are two pieces of ribbon that are equal in length and a plastic headband. This headband can have two colors or one. Start by taking one ribbon by the end and fold it back on itself to form a loop. Take the second ribbon and wrap one end around the base of the first ribbon’s loop, then tie it into a secure knot. Make sure to leave a short tail on each ribbon for the end of the bookmark. Note that the tails should be on the same side of the longest tail on the first ribbon. This step should also leave the length of the first ribbon hanging down. You should be able to gently pull on this longer tail to adjust the size of the loop. Once the knot is secure, form the second ribbon into a loop (just like the first loop you made) and thread it through the first loop and pull the first loop’s tail down to secure the second loop. Make sure to leave this as flat as possible and not bunched. If it becomes bunched, you are pulling the loops too securely. Now that you have completed this, the rest of the project just repeats itself from left to right. So, at this point you should have a loop on the right side. Pull the right hand ribbon through this loop and secure it down with the ribbon on the left. Now you should have a loop on the left side. Repeat this process until you have created a the braid as long as you want. To finish the bookmark, instead of forming more loops, pull one side of the ribbon all the way through to create a free end. Pull the other end up to match this one and finish with a simple overhand knot. Make sure this isn’t pulled too tightly or it will smash the final braid. Now, by using hot glue, simply attach the chain to the headband.
