This technique is called the Vellum Overlay card. You need to use a good quality of vellum for this as well as embossing powder and line stamps. I found the perfect stamps at Gina K Designs. The two that I used are A Year of Flowers 3 and Wild Blossoms.
Following Jennifer's instructions, I only made one change. I used a larger card stock base under the vellum, as I thought the card would be more easily handled and hold up better for mailing.
After stamping the cascading flowers on the top folding base card as I wanted them to be, I colored them with copic markers. I stamped the vines with Grass Green ink from Gina K Designs. Then inserted the base into the vellum and stamped exactly over the top with versa-mark and white embossing power and heat set them.
Thanks for stopping by to see how I made this card and I do appreciate comments. I hope that you take some time to enter the challenge this week. Your project does not have to be complicated, but this one is easier that you think. Hope to see you at the Mod Squad Challenge.
