Well, here's a necklace I made about 3 months ago... it was actually my first "real" craft project:)
I got some wooden beads(3 different colors came in a package), "leather" strap, and a pendant from Michael's. Oh, also some pins, jump rings, and other basic stuff like that. And in less than 30 minutes, this came up!
I just tied some knots to make the beads stay in place(obviously, not the best method), but it works fine for me
