When you trim the eye pins on the 3 bead sections, retain two of the pieces to use for the shorter 2 bead section instead of using another whole eye pin.
Open the larger jump rings and slide them into the crystal teardrops (15mm no longer available). Carefully close the jump rings so you don't chip the crystals. For detailed instructions on opening and closing jump rings, and on making beaded eye pins, see Basic Jewelry-Making Technique Sheet (PDF).
Made beaded eye pins in desired pattern, paying attention to the direction your loops on each section face, so all your large jump rings will face the same direction. Attach beaded eye pins directly to the filigrees, and use small jump rings to attach the crystals to the filigrees.
