To make these lovely paper dahlias first cut square pieces of colored paper in one or two tones as shown. After that make cones out of all the square pieces of paper. Then hot glue the cones to a disc of cardboard in concentric circles as shown. Make as many as you like and decorate your walls. If you want you can experiment with cones in multiple shades of a same color or you can also go for contrasting hues for a fun look.
