Place a sheet of scrap paper on the table to protect the surface underneath.
Arrange several leaves on top of the black paper, vein-side facing up for clearer texture.
Secure the leaves lightly with small pieces of masking tape if they tend to shift.
Hold an oil pastel on its side and gently rub over the paper where the leaf is placed.
Continue rubbing until the leaf shape and vein details become clearly visible.
Switch colors and repeat with different leaves, overlapping slightly for a fuller design.
Wipe pastel residue from hands and let the artwork rest before handling or displaying.
