Hang shirts and tops with the tails pinned at the side seams, prevents "humps" at shoulder seams.
Pin the side of one piece to the side of another, uses less pins.
Knits are better hung on a hanger, then the hanger onto the line.
Undies can be hung with one pin.....
Oh yeah, check the daily weather report... You may have to run to the store when an unexpected shower comes along!
Hmmm, been awhile since I did this but it's coming back!
