To make two 40-inch x 68.5-inch curtains: 

• 4-1/2 yards Global Weave Embroidered Yellow Branches
• 4-1/2 yards Kona Cotton in White 
• 1 large spool Gutermann 100% cotton thread color 1006
• A pair of tweezers

Cut each 4-1/2 yard piece in half so you have two 2-1/4 yard pieces of both the Kona Cotton (lining) and the Global Weave (outer curtain). Wash and dry the fabric. I highly recommend getting each piece pressed and lightly starched at a dry cleaner. It's very hard to iron such a large piece evenly, and the name of the game here is even. (As an added bonus, after I got my fabric pressed and starched it had a delicious cinnamon toast smell.)
