i am not expert in beading technique, so i always look for simple techniques for beading.. few days back i saw snowflake beading pattern on you tube.. i slightly modified it ( i should say simplified for myself).. and made this pendant

for making it we need
-size 12 needle
-2 colored beads
-crystals beads
-thread
-scissors

Step 1:

take three 1 colored beads and pass through needle and thread
make a tight knot. this will result in a small triangle
now pass a needle through neighboring bead, this will lock the knot
now take 1 same colored bead and pass it through next bead
again take 1 bead and pass it through next bead
now take 1 bead again and pass it through next and new bead (please refer photo)
this will again make a triangle

Step 2:

now take 2 2nd color beads and pass needle through next corner bead
take 2 beads and pass needle through next corner bead
again take 2 beads and pass needle through corner bead and one next 2nd colored bead

Step 3:

now add one 1st colored bead between tow 2nad colored beads
also add 1 1st colored bead in between 2 distant 2nd colored beads (refer photo)
complete circle
you will need total 6 beads
at last bead pass needle through 1 2nd colored bead and 1st bead of newly added beads

Step 4:

now add 2 2nd colored beads between the 6 1st color beads
at last beads pass the needle through 1 1st colored bead and one 2nd colored bead (refer photo)

Step 5:

add 1 1st colored bead between 2 2nd colored beads
also add 1 1st colored bead between 2 distant 2nd colored beads (refer photos)
complete round
at last bead pass needle through 1 2nd colored bead and newly added 1st colored bead

Step 6:

now add 1 1st color bead in between 1st color beads
complete round
at last bead pass needle through old 1st colored bead and newly added bead
if you want you can stop here
or may proceed to next step

Step 7:

now add a crystal bead
and take 1st colored bead
and pass the needle back through crystal bead
and pass this through neighboring 1st colored bead
you can go on adding these as much as u want (max 12- for round)
i have added only 3
while adding crystals please take care because these things make whole structure little loose (because of that only i added only 3)
finally tie knot
pendant is ready
