Where I live one of the latest crazes for kids is "Silly Bands", which is basically colored silicone material in fun shapes from words to themed shapes such as trucks, sea creatures, dinosaurs and girly items and even some celebrity shapes.
I bought a package of 12 dinosaur ones at Kroger for $.99 cents, but if you don't have them where you live they are sold on E-Bay http://shop.ebay.com/?_from=R40&_trksid=p3907.m570.l1313&_nkw=SILLY+BANDS&_sacat=See-All-Categories.
As they were too small for my wrist, I crafted them into a necklace. It is a fun piece to wear but one word of caution is that if you have long hair, you might want it wear it up if you wear this necklace because the ends can get tangled and snagged in the bands.
Pick out which shapes you want to use and how you want the positioned on the necklace. I used 10 bands for my necklace.
Use the jump ring tool (you can DIY one - instructions here: http://www.cutoutandkeep.net/projects/diy-jump-ring-tool) or the pair of pliers to twist each of the jump rings open.
Hook one jump ring to each end of the Silly Band then use the jump ring tool or pliers to close.
Then use a jump ring to connect the jump ring on each end of the Silly Band. To make sure they stayed connected and pushed the rings together with my fingers so they overlapped a wee bit and it was ready to wear in about 10 minutes!
