“Corrugation Nation,” Waterfall Arts’ open-call cardboard exhibit, has been a very popular since it opened in April. To celebrate the creativity of all who took part, Waterfall Arts will hold an end-of-show party with a raffle of some cardboard pieces in the show.

The free party and raffle will take place on the last day of the exhibit — Friday, May 18 — from 6 to 8 p.m. The family-friendly event offers refreshments, a live band and announcements of the best-of-show winners, along with the raffle of more than 40 cardboard works of art included in the show. The pieces were generously donated by the artists to raise funds for Waterfall Arts programs.

Raffle tickets can be purchased at Waterfall Arts, 256 High St., or by calling 338-2222, two for $10 or six for $25. On the night of the party, raffle ticket holders or their proxies must be present to win an original piece of cardboard art, some of which can be seen online at waterfallarts.org.

Now in its 13th year, Waterfall Arts is dedicated to creating community in harmony with nature through the transformative power of the arts. For more information on the raffle, classes, artist residencies, studio rentals and events, visit the website or call 338-2222.
