Get some pvc pipe, proper end fittings, cut to size, glue and done. Decorate if you like
I wrapped mine with three different colors of yarn, used 1 1/2" pipe for 6'6" 3pc 3wt fiberglass I just finished building. Get some felt pads for furniture and glue them inside of end caps, this will cushion the rod. For a cloth bag I ripped up an old pillowcase with polka dots and use it as a wrap.
