I was desperately looking for a 6 inch ring for my "ring and rubber band plus" trick and after having considerable problems finding something that would work I found a great source of colored plastic rings on ebay. The 5 inch, and 6 inch rings I found there are used for macrame pocket book handles, and there is a wide selection of colors to choose from at a rediculously low price. They also have some square pocket book handles there that would work well for a change of pace on any ring and rope routine.
