I've had a couple of days off the challenge, so am playing catch up once again.
Here's my Day 20 card. I've used a Penny Black clear stamp from their set called "Animal Wisdom" stamped in Versafine Clair "Nocturne" black ink and coloured with "Wild Honey" Distress Oxide Ink.
For the background, I have used the Funky Fossil "Honeycomb Background Stencil". I first coloured the white card with "Wild Honey" Distress Oxide Ink, I then used the same ink through the stencil to create the pattern.
