LOS ANGELES (AP) — Carrie Underwood just won another Grammy, but the question everyone is asking her: how did her dress work? Underwood performed “Blown Away” on the Grammys in a silver dress that started drawing curly designs across the front, then sparkles, then hearts that fell into petals and a monarch butterfly.

Underwood says the trick was a projector and a specially-made dress that acted as a screen. She jokes she wants to take the dress home so she can watch movies on it. Underwood won the best country solo Grammy for “Blown Away,” and that song also won the country song Grammy.
