Try method that paul @redfishbluefish taught me
Take some plastic mesh from like a bag of oranges or a $1 store dish sponge. Cut it up, enough to wrap around a piece of rock, rubble or frag plug. Place the clove inside the mesh, wrap it in the plastic, and just wait a couple of days.....eventually the clove should attach itself to the rock or what it is.
Wrap it tight, but not too tight so that the clove can extend out like it normally would.
