I love Overlays!
You will need a transparency to stamp on, a piece of paper, a permanent ink, an acrylic block and your favourite stamp. I used Penny Johnson´s “Chanson d´amour”.
Adhere the clear stamp onto the acrylic block and use your permanent ink on it. Put a piece of paper beneath the transparency, this will allow you to see exactly where to stamp.
Stamp the image as often as you like. Voilá here is your Overlay. Cut it and use it on your project
