Тhis is a very easy and impressive card (we already gave it away to a beloved friend). You need an empty foam tray, a heart-shaped cookie cutter (to make your shapes more regular) and some tempera paints.
Cut out a square from the bottom of the foam tray. Press the cookie cutter into the square to leave an impression, then press along the indentation with something thicker (we used a pencil) to make the lines wider.
Make several prints in a row with tempera paints. Clean the styrofoam ‘stencil’ well after each color so the hues on the paper will remain clear. When the picture is dry, cut it out an glue it on colored cardboard paper.
