Texas Hill Country The three patterns here represent three of the prettiest rivers in the Hill Country - Bandera, Llano and Rio Frio. I've attempted to catch in visual form the mood of each river and its adjacent banks, with the blues representing sky and water, the browns representing sand and earth, and the yellows representing the sun, stars and flowers. These patterns use wavy lines, bands and stylized flowers to encapsulate a sense of calm, vibrant nature.
