Bottle Cap Texas. Outline of Texas covered in bottle caps to look like the Texas Flag. Dimensions are approximately 23 1/2" by 23" -- longest point to longest point (El Paso to Gulf; Panhandle to Brownsville). Caps are flattened and then nailed to 1/2" plywood. They overlap so you only see bottle caps, no wood. The edge of the plywood is painted to match corresponding color in the flag. Star is made from metal. Hanger in back is balanced and the hole has been notched so it hangs flat against the wall.
