Thread painting is an art form that involves folding paper in half and using a piece of thread dipped in different paint colors to create a pattern or design on the paper. The thread is dipped in various paint colors and placed in a pattern on one half of the folded paper. The other paper half is then folded over and a book is placed on top to press the paint from the thread onto the paper, leaving behind a unique design when unfolded. Children can enjoy thread painting as it allows creative expression and development of imagination through simple art.
