A three-panel or three-section work of art. I didn't know, and in case you didn't either. That's what Wednesday's Stamper called for in their challenge to create a tryptich. (Turns out I didn't quite read the challenge correctly and it should be ATC size.)
I used an arch type panel for mine. I added orchid ink to my paper and then used various stamps: Hero Arts and Paper Inspirations for the background. Romantic couple by Inkadinkado.
