Here's how to turn your window screens to get them in

When you measure for new window screens for your house, you have to know what kind of windows do I have ? 

Sliding Windows, Wood Windows, Casement Windows, Vinyl Sliders
  In this lesson were gonna be talking about sliding windows, the ones with slots that the screens go into, if you measured from the deep slot to the edge of the shallow slot then you just put the screen into the two deep slots first "right ?" wrong
They wont fit, so the answer is to just turn the screen and kinda wiggle it in like that, works for me every-time.
