Initial Masking of a Small Window's Top Edge

Wind picking up once the blow on my masking away, but I'm not gonna get frustrated. I can just grab it, tack that down quickly before it starts blowing around again. So I'm gonna be masking a window right here. I'll show you a small window how I go about masking this. So I'm gonna put it about a half inch quarter inch. I'm gonna roll it out. I'm gonna gauge, I'm gonna look. Just take your time, get it right where you want it. Snap it, pulls my line. Now I'm gonna pull this tight, tack it down. Now the wind starts to pick up a little bit.
