After lighting the Shabbat candles, women traditionally wave their hands three times in front of the candles, semi-circular inward-leading hand motions. The hand waving is a symbolic greeting for the "Shabbat Queen," ushering her holy presence into the home. After the third wave, the hands end up over the eyes, and the woman recites the blessings on the candles.
