Found a cute little project that uses wine corks to make key chains.
key chain rings
Pre drill the corks with a small hole through the center lengthwise. Then taking a head pin, add on a bead or two. then tread the head pin throught the cork and add another bead. Then using plyers make a loop on the end.
Then add the key ring to the loop with a jump ring. and you are done.
Hope you enjoy making these.
