Requirements: red foam sheet, red and blue foam tiles cut into small squares (pre-cut optional), pencils, scissors, glue.
Instructions:
- Draw a heart on the back side on the red foam sheet and cut it out.
- Take the (pre-cut) foam tiles and place the blue foam tiles on the outer edge of the foam heart. We placed two rows around the edge.
- Continued on the inside of the heart with the smaller red foam squares. Start on the outside and move towards the inside of the heart until complete.
