While line drying does lengthen the life of your clothes by not sucking bits of them into the lint trap, it doesn’t remove loose lint and pet hair (a big deal in our multi-pet household). You can toss any line dried but “furry” items into the dryer set on air fluff, with an all-natural dryer sheet, to loosen and remove offending fibers. I don’t have a dryer anymore (it gave up the ghost last year, and not replacing it was part of my 2008 carbon footprint reduction effort), but I do have a secret weapon: A damp hand rubbed firmly over the surface of hairy or linty items picks up the offending fibers better than any lint or pet hair remover I’ve ever tried.
Extend the drying season.
Drying laundry indoors can be an option, though in humid weather it will take a long time, boost indoor humidity levels, make your AC work harder, and perhaps exacerbate any mildew problems. In dry climates and in the heating season when indoor air tends to be too dry anyway, drying lines or wooden racks in the house are a great option. I have wash lines in my basement for winter use, and I use a box fan to move air gently through the drying laundry to speed up the process. In spring and fall, you can hang wash outside on cold days; try wearing rubber dishwashing gloves (or a larger size of rubber gloves over a thin pair of winter gloves) to keep your hands warm while handling the wet items.
