I've had some emails asking how I did my attic window back in 2008 so thought I'd post the answer here with a picture of another one I finished this year.
So I started with a panel & cut it into 9 equal pieces then added sashings to the left and bottom using the method in the links below. Then I sewed 1/2 inch black sashings around each block. After I took the picture posted on the forum then I also added a 3 inch border around the whole thing - made it look more like a real window. The one below has it too.
