I am to the point of putting screen on my porch of my shop. I am considering doing it myself using the SnapP aluminum extrusions.

The openings are about 9' wide which is my concern. I might have a lot of trouble getting a piece that wide straight and smooth. I understand from youtube videos that the only difficult thing is getting the first spline into the screen at the top in straight.

Any advice or experience with screened porches is welcome.

Thanks
