One day I found this large, metal key sitting where someone had thought fully left it sitting in the unfinished wood section of JoAnn Etc., where I was working at the time.
My first reaction was to curse whoever had felt it unworth their time to walk it back up to the front of the store where it belonged. The second was "Wait a minute. That's actually about the right size for a Keyblade."
I grabbed my Kingdom Hearts crazy co-worker and showed it to her. We tested it and yup. Just the right size. Of course, it was a fairly unappealing bronze colour with a HORRID false patina on it.
It was also half off and under a week until Valentine's, so she bought it and I found myself on the recieving end of "Please paint this and make it look not tacky so I can give it to my husband pleeeeeeeease!" face.
(Okay, so I'd volunteered. I still got The Face.)
This was painted with Duncan acrylic paints. The metal is antique gold and bronze. The irridescent red and green are a base colour with coloured, pearalized paint over the top. The dark green on the shaft is the same colour as the undercoat on the leaf. I left it matte to help ground the key. The whole thing is finished with a matte varnish, except the red "jewel" down by the leaf and the center of the flower. Those got hit with high gloss.
The back looks horrid, but that's because they did a CHEAP job of making it. Fortunately, it's meant to hang on a wall, so it doesn't matter. Still, it would have been neat to make it actually functional as a Keyblade. ...ah well. It was a ton of fun to make. I wound up buying a second one to do for another friend.
Edit: Since people apparently can't get over it - no, these things don't have handles. They're converted wall hangings. They were never meant to be wielded!
