There are more than a thousand ways to do it. Most are pretty good. A few are not.
This is what works for me.
Start by reviewing the weather. A large spread between the dew point and the predicted temperature is good (low relative humidity). A low probability of precipitation is also good. Sun is great. A breeze is good. Gale force winds are not good. There is not much drying power in the first two or three hours of daylight in Michigan. That may not be true in Arizona or Western Oklahoma.
Your success rate will vary. Get used to the idea. Day length varies by time of year. I was able to get 6 loads washed, hung, dried and back into the house today. But today was an exceptional day.
Start by washing the items that are large, heavy and/or cotton. Things like towels, sweat shirts, and jeans. Hang these closest to the poles. Hanging them close to the supports will minimize the chance of them dragging on the ground. Washing them first gives them the longest time to dry.
|Large, heavy items close to the support. I can pack more per foot of line by hanging long-way down. I can hang short-way down in the middle of the span where the line sags.
|Minimize overlap. The clothes pin is pinching four layers of cloth together and this will be the last part of the item to dry.
|Undies merit special consideration. Do not hang them like this.
Turn those rascals inside out to most fully expose the discolored portions. And then hang them up-side down. This is one time when being azzbackwards is an advantage.
|People brag about "We don't air our dirty laundry." That tells me worlds about their priorities.
|This is one place where you do not try to minimize the amount of fabric pinched by the clothes pin. You want to fully expose the 'discolored" area to the sun as possible. Note that pin is not centered on the article of clothing. That is OK.
Socks can be hung two-at-a-time.
You don't have to line dry everything to kick OPEC in the teeth. My washing machine can wash a "Super" load in 40 minutes. It takes 90 minutes to dry. I can un-bottleneck the drier by washing a mix of large, slow-to-dry items with each batch of small, synthetic, pain-in-the-butt items. Then I hang the slow-to-dry items on the line and pitch all those itty, bitty items into the drier.
