Amazing piece of vintage Waverly!
Sketchbook Collection: Gridlines
Measures: 2.55 Yds (93") Length x 49" Width
Color: Hunter green with gridlines in tan, burnt orange, wedgewood blue, and crimson red.

Fabric from the Sketchbook Collection by Waverly.
2" square gridlines design
I do not know what the exact fabric is but it is a heavier almost canvas like fabric with a Scotchgard finish.
Would work great for upholstery or curtains.
