Add beads to the head and eye pins, and make simple loops. Try to keep all your loops the same size.
For the top beaded eye pin (that connects the ear wire to the filigree finding), make your loop perpendicular (90 degrees) to the original loop, so the earring hangs straight. If necessary, use 2 pairs of flat-nose pliers to adjust the angle.
Open the top loop of the eye pin, rather than the loop on the ear wire, when connecting all the components.
