I have quite a few colours of pearl embossing powder that must be over 10 years old (yes - I'm a hoarder!) When you look at the pots, you cannot tell the difference, but when you use them on dark cardstock, they really shine!
I used a navy blue cardstock, stamped in stages with versamark ink and the corresponding pearl colours ... leaves = green, flowers = red (came out a bit violet with the blue background) and heart centres = blue. The sentiment was embossed in white. Added white gel lines and dots for effect, but in retrospect I think I should have left out the lines.
Here is my 3x3 card - perfect for the OLW139 3x3" card challenge and the Less is More 119 One Layer Coloured Card challenge. Also entering for Annabelle Stamps Anything Goes challenge as I used stamps from my newest set "All Squared" from Annabelle Stamps.
