Four adults, two separate houses due to working away. Also a holiday let. Lots of laundry, bedding and towels.
We have a basket per person in our bedrooms.
I wash when the basket is full. Never mix baskets to reduce sorting, this works like a dream.
Whites basket in bathroom. They have a separate wash when basket full. This is mixed but is minimal sorting so I'm good with that.
Work shirts get a separate wash, no softener. I iron shirts.
Bedding gets washed together, this can be up to 8 beds some weeks so several washes. Change bedding every week.
Towels get a separate wash, every week. Dirty towels get put in the bath so I can easily see when a wash needs doing.
No set days for laundry, I like to peg out which means I'm governed by the weather. I'll put off washing if I know the weather will be better later for drying.
I have a tumbler but try not to use it as I prefer to peg out. I never tumble our clothes only bedding, towels and smalls. Either peg out or use my sheila's maid or heated airer if its raining.
To reduce sorting, I take out separate baskets when I'm bringing things in off the line, as I unpeg the clothes get folded (if its not raining) into the separate baskets. I have 6 of the woven addis baskets, they stack into each other when not in use.
Also, I have a lot of clothes so there is no real pressure to turn laundry around quickly. Dh has two sets of working away clothes (more like three) I do a set for him to take away and turn the dirty set around during the week. I keep our weekends as free from housework as I can.
Ironing gets done when I can. It is a sticking point for me, I enjoy the results of it but sometimes its just too hot or I'm too tired to bother. Have invested in a Fastpress which is marvellous. Also have a steam generator iron for doing shirts.
Laundry is never ending and I'm over beating myself up with frustration that its not all done all of the time, so I've tried to make it as easy as I can for myself.
