Hi Ladies!  I'm new to the group, but just completed my first DIY project tonight- my mock-up centerpiece:

Here's the step by step:

Materials:
-the "vase" is actually a black party cup- picked them up at Michaels after halloween- .47 for a pack of 4!
-Sparkly spiral branches- can be found at Michaels; I found them in the Christmas section
-Black branches with crystals- found at Pier 1, again, part of the Christmas stock
-some foam to put inside the vase (purchased at the Dollar Store)
-some black garden rocks (Dollar Store)
-Silver sparkly Christmas Ribbon (Michaels)

Steps:

-put a couple rocks in the bottom of the vase to weigh it down
-insert the foam into the vase
-stick in the branches (stick them through the foam)
-cover the top of the foam with more of the decorative rocks
-tie the ribbon around the vase; fasten with glue or double sided tape

Ta-da! :)

Very classy! I like that foam was used: easy to deal with and not really messy.

These are SO pretty!  Great DIY!  What do you figure your cost is?

cute!!! i really love it

WOW!  I never would have guessed that you used some of the stuff that you did!  They are very classy and overall stunning.  What was your cost breakdown?

I love it:)!
