For this Rainbow Loom bracelet I figured out how to connect two bracelets together to make one long and wide continuous bracelet with just one loom. Usually you would have to buy two looms and connect them together to make a long bracelet, but in the video tutorial below I will show you how to connect two bracelets together to make one seamless bracelet. The other alternative that I've seen is to create a small extension and add it to the end, but it doesn't really look that great. This tutorial will show a better way of making a long rubber band rainbow loom bracelet. The beginning of the tutorial is a beginners tutorial for making a simple triple single loom bracelet. When I start connecting the bracelet it does require a little experience making bracelets (experience meaning you've made one or two). I will also have a follow up video tutorial on how to make a quadruple single loom bracelet, which you could also extend to a quintuple single Rainbow loom bracelet.
Rainbow looms can be purchased at ConsumerCrafts.com and Amazon.com. There are also other brands of rubber band looms such as FunLoom, Bandaloom and Cra-z-Loom. They are all basically the same concept (not sure hot the patent works for it!)
