Use painters tape to measure how far apart you would like your screws or nails to be. If this were a picture you would measure from the center of one hook to the center of the other.
Pull tape from the back of what you are hanging and center it. At this point, you can use a level to make sure it is not caddywhompus. If you are like me, you eyeball everything and don't need it.
I am drilling for wall anchors/drywall plugs. Use these when you are not directly screwing or nailing into a stud. *hee hee* This keeps your wall hanging from ripping a giant hole in the drywall.
Hammer your drywall anchor in. I always think I can just bang one in with a shoe or a hard cover thesaurus. Today I tried a box of business cards. It never works, they always snap. Get the hammer.
Screw your screw. Nail your nail. Pin your pin. Whatever it is, leave a 1/8 to 1/4 inch protruding - depending on what is needed.
Thanks again! She really is snoozin' hard....
