Great video Tim! The window part of the canvas was the most challenging job of the project for me. Mine came out probably a 5 out of 10. If I wasn't turning 70 y/o next month, I think I might attempt to build another set. For anyone attempting the project that has no sewing experience, I'd advise you to buy a little extra material and make a few practice window panels. They are a little tricky to make. By the time I got to making the cushion covers and curtains, my sewing skills improved greatly.
70! A great accomplishment. Congratulations. I couldn't agree more about taking the test runs before making the final windows. I made a ton of paper templates as I figured all the folds and seams out. I also borrow a domestic machine and just made some simple seams to get acquainted with sewing. I found the sewing, like so many things (woodworking), is all about the prep and set-up. The machine is only on an stitching a for a small amount of the time, most of the skill comes before the thread enters the fabric.
My wife and I are looking forward to the curtains and cushions, we agree they should be a walk in the park compared to everything else.
