I put this on the bench to show the process. I have sewn the entire red pocket on with another row of variegated thread zigzag. I chose to only have a small vinyl pocket because I didn't know how strong the screen was going to be.
This picture shows a portent of the next step as it will be folded into a bag.
MISTAKE.....The screen stinks.after being in the garage for 5 years. ..I should have washed it out in sudsy water, but didn't think of it because I was hot to sew this bag. It is too late now because I am not ready to see if the bag can be washed. I will just air it out on a windy day.
