You will need:
-Plain wreath (Any craft store)
-Green Carnations (Dollar Tree)
-Green Glittery Shamrocks (AC Moore)
-Bow (AC Moore)
-Shamrock sign (AC Moore)
I started out with taking the bunches of Carnations (8-10) and cutting each individual flower about half way down.
The last thing I did was take a twisty bread tie and attached the sign to the wreath.
That was it....Easy breezy!
