I put a tea light in mine because I have no cupcakes on hand.
I got everything at the Dollar Tree except spray paint ($3 at Home Depot) and the cabinet knob ($3 at Home Depot) and the E6000 glue ($5 at Joann's).
The tutorial I read used a 50cent wooden knob instead of a cabinet handle.
It's a med/small fish bowl for $1 and a candle stick holder for $1 and a flat candle holder for $1 all from DT.
I spray painted them hold and then glued the candle stick holder to the bottom of the plate candle holder. Then glued knob to bottom of fish bowl. Don't paint the top of the flat plate candle holder because that's where the cupcake sits.
