This technique is a bit of a mouthful, but calling it the “wax paper emboss resist technique” describes it best. The first step is to emboss a piece of wax paper with an embossing folder. The more detailed the embossing folder, the better this technique will look. The second step is to iron the embossed wax paper between two pieces of white card stock. You will not be able to see the wax that melts onto the card stock, but when you apply ink with a blending brush, the design comes to light. Here are some samples. You can see that the wax on the card stock resists the ink. One will appear to have less wax than the other, usually the piece on the bottom.

To finish the card , we trim down the blended panel and add a coordinating color layer. Then, add a die cut floral bouquet from Hand-penned Petals that is popped up. A die cut circle sentiment is layered with a scalloped circle. The inks we used are Petal Pink and Flirty Flamingo.

Keep in mind you can try this wax paper emboss resist technique with any products. If you want to recreate this card using a currently available stamp set, I could suggest Petal Park that you can purchase at my online store. And, while the embossing folder we use for this card is also retired, consider any embossing folder you have in your stash, or select one to purchase from here.
This stamp set is no longer available, but if you are interested in other cards that I have made with it, you can find some here.
