The Swarovski crystal beads for this project include what is referred to as modular beads (#5150) and side-drilled heart beads (#5742). The modular beads look as if they are two beads stuck together or sort of bow tie shaped, and the hole goes through this dip between the two sections of the beads. So, to me, they reminded me of bow ties. The heart beads, as the name suggests, has the hole drilled through the side rather than down the middle of the bead.
