In one sentence, describe what the following article is about:

All the pieces of this puzzle are identical, though some may be different colors. Choose any piece to begin with and lay it down vertically on your table or work surface. Each piece has triangular-shaped "peaks" that stick out as well as triangular-shaped "valleys" or indentations for the "peaks" on other pieces to fit into. Use a piece in a different color than the first. Turn the new piece sideways so the peaks point outward, and situate the middle peak of the new piece into the farthest valley, or indention, of the first piece. The pieces should be perpendicular to each other. Choose a piece that is the same color as the last 1. Turn it sideways and fit it into the closest valley of the first piece so the 2 are perpendicular to each other. The peaks should be pointing toward the last piece you added. Select a piece that is the same color as the first piece. Flip the new piece over so the peaks and valleys face downward and it is parallel to the first piece. Nestle it on top of the 2 stacked pieces. At this point, you should have 4 identical pieces that are interlocked. Turn the puzzle sideways so that there are 2 pieces pointing vertically. Hold the puzzle in 1 hand and use the other hand to slide a piece horizontally in between the 2 vertical pieces. Turn the puzzle over so the last piece you added is on the bottom. Slide the last piece in between the 2 pieces that are sticking up vertically so that it is parallel with the last piece you added. You may have to wiggle or manipulate it a bit to get it to fit. You've now solved a 6-piece wooden star puzzle!
Lay down 1 piece vertically on your workspace. Stack another piece in the farthest valley of the first piece. Slip the next piece into the closest valley of the first piece. Stack a piece on top of the last 2 pieces. Turn the puzzle sideways and fit another piece in between the 2 vertical pieces. Flip the puzzle over and fit the last piece in between the 2 vertical pieces.
