I have a porch that measures about 5x8 I want to screen it in.
Deborah, I love a screened porch. Hopefully one day we will have one again. Here is a tutorial for making one. I hope it helps and enjoy it in this beautiful fall weather! https://www.hometalk.com/8941520/breezy-bug-free-screened-in-porch

We had to have our two porches rebuilt. My husband made the screening for the lower porch. First pic is of the screening we installed some years ago. Our porch is 7' X 14' as you see we had to have supports for screens to be fastened to.
Harbor Freight has pre-hemmed garage-door sized screen panels that can be literally stapled into a wood header and rolled down.
With the 20% off coupon, it’s cheaper than I can buy rolls of screen.
