And that's what I used to make these:
Use hot glue to attach some yo-yo's to the front of a blank card. I attached some ribbon first for some added color.
You could also attach a yo-yo to a paper clip to use in your office to bundle papers or you can use one as a book mark.
Or you can add some to your favorite black dress.
Or a shirt, or a purse, or anything else you think of.
