You will need:
Coloured glue-gun glue
Lay parchment paper down. With the glue gun, spread a line of glue and place beads on top.
When you have reached the desired length, wait for glue to cool, then peel off parchment and glue both ends together.
Feed the yarn through a needle and then feed through a bead then wrapping around and through the next bead, continue until you have threaded all the beads.
Repeat another round, this time wrap the yarn around in between each bead. Tie a double knot.
