DIY- candles. You can use any clear glasses, even old flower vase. My favorites are the antique glasses that weren't doing anything but collecting dust, and a collectors glass I purchased on a vacation. Just pour colored wax beads and place a wax coated wick in middle. You can also add your favorite fragrance as you add wax beads to enjoy as you burn the candles!
Beaded candles - inspiration only - would probably apply these to the glass, since dripping wax would ruin a lot of work otherwise! Make collars, pin to candles, to burn, put rubber band around candle jar & lower collar to cover it, then put candle in jar to burn - best of both worlds :)
