well, this is kinda silly..
it's not too hard to figure
out on your own, but i
 needed an excuse to
 use that swoonable pic!!! 
 i know you understand =)

ok, so...
Materials:
~ string (well duh)
~ Lots of white beads
~ Lots of blue beads 
( i like the light blue ones...)


What you do:
~tie a knot at one end
          (duh again)
~ string on 6 blue beads
~ string on 6 white beads
~ 6 blue
~ 6 white
....you get the picture
~then you can either just tie the
 ends together, or tie on clasps

Viola! You've got Davy Beads!!!!! =)
