Hanging laundry without digging posts?

Do you have trees? I have a rope tied to our stockade fence post, around a nearby tree and then back to the next fence post down. Not perfect, but it does the job.

You could also run a pully line from the corner of your house to a tree.

I could think of other solutions, but I don't know what your house setup is like. They have retractable clothes lines (four or five lines wide) that you could hang on the house and hook on to, say, a nearby garage.

Mine is in the garage between two sets of metal shelves.

I have the single retractable line type that is screwed into the exterior wall of the garage, and it stretches across the backyard and attaches to a hook on the kids' swing set (it's a wooden structure). I have to prop up the middle with a wooden pole after everything is hung. I suppose you could do the same, you just need a structure to fasten the reel and the end of the line to. Do you have a fence or a tree?

smallish trees and a low chainlink fence.

I loved my rotary line. Could be removed for lawn mowing as it fitted into a sunken hollow rod. It also held more than one full load of laundry without taking up excess space.

These are soo much cheaper in England!!!

My mom has the "umbrella-style" clothes line. It required digging a hole, into which she buried a bucket with the concrete. I'm not sure whether the hole in the concrete was something she did herself as it solidified or if there was something that came with the clothesline setup that went in there.

Once the concrete was set the bucket got covered with a bit of grass (except for the hole for the post of course). This way you can put the clothesline post in or take it out, as needed. When she moved she just dug up the bucket and we took it with. It would be a weekend project but she did it herself so I don't think it's too difficult.

My clothesline is strung between two sections of fence (in my case it's across the narrowest part of my yard, but it would work in a corner too.) DH screwed a couple of those really big eyebolts into each section of the fence, and then we used stainless steel latches to attach the clothesline to the bolts.

Mine is the fancy 'rope & two trees'.

Not cheap unless you already own one, but I've always wondered if you could use a patio umbrella base as the base for an umbrella clothesline. No hole-digging, no concrete, and completely moveable. Anyone know? Or would it not be stable enough?

Not a clothesline, but I've been collecting drying racks (obsessively!) at yard sales and I have a collection of them that I can hang out several loads of laundry on. I would rather have a large Amish-style pulley clothesline, but we don't own our home and it's nice to be able to move the drying racks so the clothes dry evenly. It does take a bit of time to arrange the clothes on the racks, but I like not dealing with clothespins
