Here's my submission~
And a close up of the details~
I used a snowflake image that has a triangular to it and colored it with markers before stamping. I then added the rhinestones on either side to give a nice triad of triangular images effect. Did that sentence make any sense? Probably not. Oh, well! It's very triangular! ;D And WHY do rhinestones defy my photography "skills" and look black at almost all times?! Anywho...
Hope you are inspired to create something triangular today! Happy triangulation! :)
