Doors and Windows - screen panels

I recently had a contractor add on to the back od my home a small closed deck. He did all the heavy duty work with the plan being that I was going to finish with screen panels and for winter removable storm panels. all the panels are pretty much different widths. I purchased the screen and spline and have a pretty good idea about how to go about it, but would appreciate some expert directions. I already havew 1x2 stops centerered in the 2x4's. I want to fit them agasinst the stops. Any ideas/ mythanks in advance::)

Not clear what you are trying to install, specifics would help or pics. I am a big fan of ScreenTite screen molding. Look for it at big box stores, and lumberyards.

You say you have purchased the screen and spline...have you purchased the aluminum frames? You will need them and the corner pieces to complete the picture. Bill, the screentite is great stuff, but not removable.

yes I have the whole kit, I bought it at home deopt
