Use cute ribbon to tie the weights onto baskets (which store items in closets) for eye-catching labels. Write the baskets' contents on the weights with a Sharpie marker.
Attach them to plain, old tablecloth clips (you know those clips you use to hold your tablecloths down while picnicking/camping?) to brighten up your table.
Use hot glue to attach them to skewers to make adorable plant picks.
Dare I say...earrings? LOL (jk)
