Colorful Spools of Thread in Display

The image showcases an organized display of thread spools, arranged neatly in rows on a wooden rack. The spools are arrayed in a gradient from warm hues of red and yellow on the left to cool greens and blues on the right. Each spool is identical in shape and positioned diagonally, creating a rhythmic pattern enhanced by the shadows and reflections on the wooden surface.

• Distinct color gradients help in assembling sections of the puzzle.
• The repetition in shape and pattern may increase difficulty despite color variations.
