Ukrainians do the same thing.
The Artos usually has the image of the Cross or the Resurrection on it. Ours has an icon of the Resurrection.
It gets consecrated at the end of the Paschal Liturgy in honor of the Risen Christ. Christ is the "Bread of Life Eternal".
The Artos is left on the Tetrapod where it gets venerated by the faithful, then it gets cut and distributed to the faithful on St. Thomas Sunday.
We also are taught to "save" it for emergencies. If one is very ill and cannot reach the priest, etc...then in place of the Eucharist the Artos is eaten.
Additionally, some people always carry a piece of dried blessed Paska bread (special Easter bread baked for Pascha and blessed by the priest in people's Easter baskets) and a piece of Artos with them at all times, especially if embarking on a journey, or a new venture.
"Я до Вас із Дарником і Паскою, будьте до мене з доброю ласкою." I come to you with Artos and Paska, be gracious and kind to me.
In the photo is the tetrapod in our church just after the Paschal Liturgy. The church is completely silent and empty because everyone is in the hall getting their baskets blessed. It is my all time favorite moment to be in church. The lights are all on, the candles are still twinkling, the Altar is open...you can still hear the hymns echoing off the walls... ...anyway...I digress!
On the right side of the icon of the Resurrection is the newly blessed Artos, still wet with the droplets of Holy Water.
