adhesive films
Adhesive foils personally pre-cut with patterns by the sand elf , from which you first remove the contours of the pattern with the help of a pick and then fill them with (black) sand.
It sticks to the adhesive layer.
Then you gradually loosen the other areas of the template and sand them with colors of your choice until 100% of the picture is covered with sand.
You can let your imagination run wild and color individual areas with different techniques, so that ultimately great sand pictures are created.
