looking for instructions on how to measure for screen door
 

This summer I was in a shop that had a curtain rod on the inside of the door frame & a screen hung by loops on it. There was a split down the center of the screen with fabric stitched to keep it from raveling & magnets inserted in the fabric so that it would close. I want to make something similar for our little motor home to keep out the bugs while letting in a little more fresh air & wonder if anyone has seen directions on you tube or another source? TIA

They aren't very expensive to buy. I think they are $10-20 in stores.

Do you know where in B.C. I might be able to find one that would be small enough?

I've watched alot of clips today.... probably won't work for our little rig as the opening is so small.... oh well....
