Here's a Fall Foliage Card for the CAS Challenge. I used one of my favorite techniques with watercolor markers - stamping with watercolor markers.
I love this stamps set. It's from Crafter's Companion Sheena's A Little Bit Sketchy - Autum Leaves.
The Aqua Marker colors I used to stamp the leaves on watercolor cardstock are: Desert, Sepia, Chestnut, Marigold, Gold, Amber, Leaf Green and Moss.
After the stamped leaves were completely dry, I splattered some of the marker ink onto the panel. To do that, I scribbled the marker on my craft sheet and then picked up the color with a wet paintbrush and flicked. To make sure each splattered color didn't bleed with others, I waited for each color do dry before doing the next.
After stamping and embossing the sentiment, I lightly sprayed some Sheer Shimmer Spritz. The panel is layered on Forest Green Shimmering Cardstock.
