Today I fixed a few of the mesh screens in our house. Leo and Adrian had a period where they liked to poke their tiny fingers through the mesh, and several bedroom windows and downstairs windows were damaged.
I watched a explanation on YouTube and in the late afternoon went to Home Depot to pick up the equipment.
On my way home from Home Depot I saw a car from Screen Mobile, a commercial service for restoring screens. No need to call them.
It wasn't hard to do, and it's nice to no longer have these ugly holes in the window screens.
