This is a currency note from the Bank of the United States and is not an obligation of the United States government. The Treasury Department did not issue notes intended for circulation as currency until 1862.
The grommet panel must be a minimum of 70 inches wide, between the side hem seams, to provide just slightly more than 1.5 times fullness on the 40-inch space.
The length and the width (at wall ends) can be trimmed. I had to trim every panel I put in my basement. The panels are 8' long and I had to trim them to 67 to 82, depending on the location. I cut them with a hand saw - pretty easily.
