To make a fun background that looks like faux marble, all you need to do is drizzle the rubber cement onto watercolor paper. let it dry and then sprinkle and spritz with your favorite colors of Brusho Crystal Colours. Here are a couple pictures of the process:
I let the rubber cement dry thoroughly then added my magical colored Brusho crystals. On the background with the light green and yellow base on watercolor paper, I added Turquoise and Orange Brushos and spritzed with water. On the glossy paper, I added Orange, Turquoise and Violet Brusho Crystals and spritzed them with water to activate the colors. On the glossy paper, the water does not soak in like on the watercolor paper, but it still resulted in a fun background. When the papers were dry. I removed the rubber cement with an adhesive eraser. This is how the pieces looked after this step, and the completed cards:
I cut the backgrounds down to fit on A2 sized cards and added some Repeat Impression's stamps and gems. The green card features one of my favorite RI stamps, Crowned Crane Deco. The violet glossy card features a sneak peak at a new word set that will be released by Repeat Impressions soon. I cut an oval with a Spellbinders die and sponged with violet ink while the piece was still in the oval die. Then I stamped "you" with turquoise ink and "did it!" with black ink. I raised this piece with pop dots and attached the colorful piece to a purple card base.
I had fun playing with rubber cement and Brushos to make these easy and colorful backgrounds. I suggest you give it a try!
