This charm has a standard 1/8 hole for attaching with a round eyelet. Or else glue it on. Tip - if you don't want to use the plain silver charm, these charms look fantastic if you sprinkle embossing powder on them and set it with a heat tool or paint them and lightly sand to give a country look. Another idea is to apply a gesso-type medium before painting them to get a 3-D look. Was $1.30
