I have seen a couple of different versions of this card -
one on Monica's blog
and one on Jo Dumbleton's blog
This is my version.
Basic Grey Cardstock inked with Basic Grey.
a) with Versamark pen and then heat embossed with White Embossing Powder
b)with Stampin' Write Journalling pen , then a drop of Crystal effects on top
c)with 2 way Glue pen and Silver Fine Galaxy Glitter on top
d) with White Uni-Ball Signo gel Pen
Basic Rhinestones embellish the sentiment.
