I used a hard white board shaped in a rectangle, painted the Google words etc, covered the board with clear cellophane so people at the Halloween party can write on it with a marker, cut out the GOOGLE letters, painted them, attached them to the top of the Google board with thin chicken wire, made my dot and painted it red, and attached it to a headband.
I put a ribbon around the board that went around my neck so I didn’t have to hold the board all night. This was an awesome and fun costume. It got a lot of complements and I won 3rd prize in a contest. The only downfall was it was a little hard to maneuver through the crowded party. It was well worth it though!!
