Firstly, Choose The Two Coulours ( Or More If You Wish But Its A Bit Easier With Less )For Your Beads
If Your Going For A More Coulourful Set Of Beads It Might Be A Better Idea Too Go For Coulours That Dont Match
Where As If Your Going FOr A Particular Coulour Theme It Might Not.

Mix / Twist The Colours Together But Not So Much That They Create A New Colour, Just Enough So That You Create A Kind Of Swirling Marble Pattern

Shape Them Into Whatever Shape You Like, I Done Circles But Most Shapes Should Look Allright

Gently Push The Skewer/Tooth Pick Through The Bead And Leave Too Dry.

When They Are Dry Remove Them From The Skewer/Tooth Pick

Use Them For Whatever You Wish =]
Enjoy.
