marine canvas window screen replacement

[Judy_Boat]

Problem - the bug screen is disintegrating but the rest of the canvas is in good shape. How to replace the screen?

This is how i think the canvas was done originally.
Step 1 - a large piece of clear vinyl with zippers was fitted to the boat.
step 2 - after that a unit comprised of a clear vinyl, bug screen and u zipper was made and bound on the outside edge.
step 3 - this unit was then placed on the clear vinyl from step 1 and sewn down.



Now I need to replace the bug screen.

My Idea is to bind an appropriate size of screen and stitch it down on the outside of the canvas. Then go back and cut out the old screen.



A very thin vinyl strip was used on this canvas for edge binding, about 1" width Does anyone know what trade name it goes by? It is not "vinyl bias binding" you find in some catalogues.
If I cannot find this I will probably use sunbrella centerfold binding which  is used on other parts on the canvas.
thanks

I find cutting a screen to shape then binding it very difficult to have it keeps its proper shape.  what I di a lot id I sew it on first piulling it tight as I go then trim it to shape and with bias sunbrella binding I sew a strip flat arounf he edge covering the screen edge
