Everyone in our house has towels, flannels, bed sheets of their colour, DD fuchsia, DS1 Royal Blue, DS2 Green, DH Grey etc guest towels are white.
Everyone's bed sheets and duvet covers are folded into the pillow case for the set and have two each.
Toothbrushes are also colour co ordinated
We have a mud room and keep out of season footwear and hats/gloves/scarves in a big plastic stack of draws, everyone has their own draw.
I have a shoe organiser over my larder door to make more room, I put packets in them mostly or cake decorations and birthday candles/ balloons in the top sections.
I have labelled tubs in a block shelving unit in one corner of the living room and each child takes a turn to tidy up each day and they know what toys go where by the label.
I have a small section of washing line pinned under the cupboard above my draining cover and peg up cloths to dry after using or washing.
A medium sized 'bucket bag' sits on the stairs which gets tired upstairs a few times a day to put things back.
I put out washing (triangle stand) and usually use one side for each child/person who has the majority of washing and then take it off and fold in order so I don't have to root around and find stuff for piles when I take it upstairs.
I time my washes so they finish after breakfast so it's less wrinkled and has all day to dry or dry in time for a second load.
If I make soup and need to freeze it I do it in portions with stand up plastic zip locks so I don't have to waste a lot of it if I just want some for lunch one day etc.
