One thing I have been using heaps is Art Institute
transparent glitter - it's really fine and my colouring with my Prismacolor pencils with all the shading etc. still shows thru, but just looks glittery. Is much easier to photograph cards too - I always find that the chunkier types of glitters (eg: Kindyglitz) tend to look gaudy when I photograph them.
The other thing I have been using alot is buttons which I invariably sew to the centre of my ribbon bow. Buttons are very popular judging by all the posts!
And on nearly every card, I use my EK Success Arrows border punch - not for the punched edge, but forthe leftover punchies which look like tiny hearts and are so perfect for adding that little bit of "
something" around an image or sentiment. See these 2 cards for an example of what I mean:
