The blind is on the window.
I used the computer to come up with a strip of paper the size and colour I wanted the window blind. I opened a Word document and inserted a text box; sized that to 2" x 6" and used shape fill to colour it. The stock greens weren't quite right so went into 'more fill colours' and found the shade I wanted. Printed it on a sheet of paper then reversed the paper and printed it again on the other side.
When the ink was dry, I trimmed the paper to the width needed for the window then added a piece of round toothpick slightly wider than that to the top of the paper.
