Summer Fun Card

Have you ever gone to make a card with a set theme and just had no idea what to do, I have spend the last two weeks trying to decide what to do with this theme and it just stumps me.  Maybe as i really am not a summer girl.  If the theme was Winter I would of just nailed it.
I have gone from thinking..ice cream cones, sunglasses, sunshine.. and then thought OK Thongs (or flip flops for those thinking..what on earth)
I have managed to work with the theme but I simply do not have any bells and whistles in this card which is dissapointing.  Then again, often i make a card that doesnt grab me but someone else likes it.  I am sticking with that theory.  You cant tell from this photo but I have cut the thongs (flip flops) from craft foam with the dotty paper mounted on it.  So they are three dimensional.  I then threaded ribbon through the base to give the appearance of straps on the thongs.  I made the thongs on the pazzles machine fairly simply, the knife didnt want to cut all the way through the foam so i did a little by hand which is fine.  I think the actual thong is quite cute and i would use a larger version of that for a pool party invite of similar!
