Turning a wine cork into a bead
How did you try to make a pendant out of the cork? A friend's mother made me a "butterbeer" necklace out of a cork for the fifth Harry Potter movie premiere, and she just wrapped wire around it and attached it to a ribbon.
I like this idea. I've thought of trying to make pendants out of corks but they always turned out bulky and not working for me. I might try this when I get home and try using a clear varnish that I have that's used for clay see if that works. I would suggest either just pouring it down the whole to just coat the inside or it might be better to dip the whole thing in a clear coat sealant of some kind in order to avoid water retention like someone mentioned earlier...
