I've used Penny Black Day Dreams (3947K) for my card. I've coloured it with Aquamarkers and added some stickles glue for a bit of sparkle!
The background has also been made using Aquamarkers.
I scribbled with them onto a waterproof sheet and sprayed them with Pearl Glimmer Mist. Then I put my glossy cardstock onto the ink and gently swooshed it to pick up all the ink. I also used a bit of scrunched up paper towel to pick up ink and fill in any gaps.
I rather like the effect of this background technique with the Aquamarkers.
Have a lovely day whatever you are doing!
Hugs and best wishes.
