As the name implies, this technique involves stamping twice to create one complete image. Firstly, stamp a large, bold stamp with a light colour, such as a solid flower stamp and allow it to dry. Next, ink a smaller, more detailed stamp in a darker colour and stamp over the first image to create a complete picture. There are several companies that produce two and even three-step stamp sets as well as inks in various tones that are perfect for this technique.
For a variation on the technique, you can use what you already have in your collection. Select a big, bold stamp and make the first impression on a piece of cardstock using a light-coloured ink. Now use a water-based marker to ink the stamp again, applying the colour to just a few parts of the image, such as along the edges of leaves or beneath flower petals. Now stamp over the first image for a complete picture. For best results, use a stamp positioner so that you are able to stamp in exactly the same position.
