Trisha Yearwood and Garth Brooks took part last weekend in a Habitat For Humanity home build in Tulsa, and the couple left its mark -- literally.

Garth and Trisha signed their names to a window frame they built in the structure during National Women Build Week, Tulsa's KOTV reported. It's not the first time either have been involved in home building, though they come at it from different backgrounds. Garth has some history in construction, but Trisha's literally learned on the job since she first aligned with Habitat.

"When I got to the first Habitat site I ever did, I actually really didn't know anything about building," she told Nashville's WKRN-TV. "I just thought the toolbelt was cute and that construction can be cute."

"After four or five builds, I've learned that a nail gun is really a construction diva's best tool," she added. "So I will not go on a construction site without a nail gun at this point. I'm definitely a nail gun diva."

Trisha will continue to observe National Women Build Week, heading to Atlanta on Sunday, The Tulsa World reported, to work on another house.

Later this year, she intends to begin work on her next album.
