Charm necklaces and bracelet are very popular these days. I’ve made a charm necklace for the puppies that I raise for Guide Dogs for the Blind. Then when they leave us to return for training I wear it everyday until their graduation. When I miss them, I can reach up and feel the charms and think that they are close to my heart.
The same principle will work for family members too. Pick a few charms that represent the person in someway. The family member could be someone who is far away for some reason or one who has recently passed away or even someone from the distant past that your family is focusing on. You could make a card to give along with the charms to explain the symbolism behind your choices. I think key chains would be a good choice for male family members or someone who doesn’t like jewelry.
