Those are cool.
I saw a large vase that had lots of small trinkets, odds and ends from around the house, glued to the vase. Maybe something was used to fill in around the pieces, then it was spray painted gold.
All that little crap people sometimes don't want to get rid of, a piece of broken jewelry that was grandma's, seashells, the old keys to the house, dice, prizes from a cracker jack box, jacks, whatever, can be used or put in a clear glass table lamp, ginger jar style.
