Lollie and her BFF took up leaning on the screen and pushed it out at the bottom of the door. I kept putting it back in but due to the numerous times it was pushed out the edges were shredding more and more...making it more difficult to get back in. My neighbor Bob was kind enough to come over and help me re-screen it with some left over screen from when the porch was added. We were concerned about getting it taut, but we did it, and were very proud of ourselves. Saved me the expense of hiring someone.
By the way, my house was built in 1906 and had one of those one person size kitchens when I moved in six years ago, so I added on 10 feet to the length of the house which is 24 feet, resulting in a decent size kitchen and a 10' x 12' screen porch. I am lucky as I have a huge open front porch and a screen porch in the back. Both get a lot of use from April to October.
