2 hole beads are all the rage. I've been coming across many great tutorials. They feature big ones like the Tila beads to the smaller ones like Super Duos and twin beads. The little beads are too intimidating for you? Then Tila beads are for you. The Tila Bead necklace tutorial by Domestic Diva is perfect for beginners. A clever use of side holed beads to help form the circle.
Also featured on Domestic Diva is this more elaborate but still easy black and white tila bead necklace tutorial. Again an imaginative way using seed beads to deal with the curves needed for this almost circular shape.
