Laundry room and computer are in the basement... so I have motivation to come down here
The bathroom door is across the hall from the basement door, so as clothing is dirty, it gets tossed down the basement steps. There is a cheap basket to catch everything at the bottom of the stairs (it's blue) and it sits in the corner so we don't trip over it. Dh is pretty good about getting anything that missed the basket into the pile so we don't trip on clothing either.
When I come down I grab a handfull, armfull, something, and carry it over to the laundry room. We really just have one big basement (except the office) so I have lots of space to spread out. I have 6 baskets to sort into - whites, lights, darks, towels/sheets, jeans/heavy stuff, delicates. I also have a small bucket near the washer for things that are stained and need special treatment.
I sort the stuff in my arms, and if any basket is full, it gets washed. I do one or two loads a day, plus diapers as needed. I come down at least 3x to check email and stuff, so it gets moved around plenty.
We only have one small closet in the house so we tend to keep shoes and off-season clothing in there, and the things we wear we keep in the laundry room. We have rolling closet things so as laundry comes out of the dryer, shirts and pants get hung, baby clothing, undies, socks, pjs get put in a large basket near the dryer to go upstairs to be put away in dressers, and the stuff that needs folded gets folded and put into hanging sweater organizers that are on the rolling closets.
My downfall is the old couch we have to keep dd from the far side of the basement. It is close enough to the dryer to be a great landing spot for all the towels, sheets, etc. and they tend to pile up instead of getting put away. And if dh "helps" he piles all the dryer contents on the pile too, rather than hanging or folding as needed.
Bed linens get changed about once a week, never more than 2 weeks, we have spare sheets, so it's just the mattress pad that gets washed right away. Things like floor rugs get washed when they need it, etc.
Someday we'll be able to remodel the 2nd floor of our home (we rent it now) and everything will change, including the door to the basement.. so I'll need a better system then, as we will have more closets to actually put things away and 2 flights of stairs.... I keep trying to convince dh that we need to put laundry in the 2nd floor where the kitchen is now - it's already plumbed and ready to go!
