Wonder no more! Here's the card I created, along with a step-by-step tutorial if you're feeling aquatic and adventurous yourself:
I started out by using the Spotted embossing folder, which I opened up and proceeded to paint with plain old ordinary watercolors. I didn't use any fancy brand of paint-- just a typical kiddie watercolor set that didn't cost much. I brushed watercolors onto the debossed (indented) side of the embossing folder, though I found that it works on either side, depending on what look you want. I preferred the look of the debossed side. Since I was using watercolors and the folders are plastic, the paint merely beaded up, which didn't look promising. I was a little scared for myself! Here's how it looked after I applied the watercolor paint:
After I removed the paper, I cleaned my folder with a baby wipe, which was super easy. As I looked at my paper, I liked how it turned out, but I am a color-holic, so I brushed more watercolor paint across the top of the card, letting it drip down to add even more color. After it dripped, I dabbed it with a paper towel to increase the blending and to remove the excess water.
I decided I wanted to incorporate a little yellow, too, so I let the card dry out a bit, then I went back in with a smaller brush and painted some of the individual circles yellow.
Once the card was dry, I added some text with a rubber stamp ("Script" from IndigoBlu) and Ranger Jet Black Archival ink.
I gave my card a "frame" by using black Gesso, which I applied with a foam brush. Acrylic black paint would also work, but I love the solid opaque coverage you get with just one coat of black Gesso.
To finish off the card, I glued on some flowers I distressed, along with a "good times" flag that I made from a strip of washi tape.
All in all, this project was a fun adventure and I'll have to experiment some more with what other mediums I can use with embossing folders.
