You can be subtle about it with some dabs of metallic ink, pearls, or metallic glue. I love how dabbing a bit of gold ink across the surface of the green ball gives it a golden pearlized effect when the light catches it from an angle.
You can kick it up a notch with some embossing, dabs of glitter glue or a sparkle or two.
Or you can go all out by using some prisma glitter along with your glitter glue or sparkles. I used Close to My Heart's Art Philosophy and Artiste Cricut cartridges to cut the tags and all CTMH products except for Color Box Gold and Silver pigment inks and Stampendous embossing powder in PEARLustre Sapphire. I am hoping now that CTMH is carrying pigment inks that they will eventually offer metallic inks.
Needless to say, with making over a hundred ornaments, I did not have time to make a card for this week's Heart 2 Heart Glitter It Up challenge. Then again, I think some of these ornaments meet the criteria... Thank you for stopping by! Until next time, Hansi
