all the bedding matches and in the case of my two girls (4 of 5 and 5 of 5) who share a room, their bedding matches with each others because it is in the same room. I do not change one piece, if it becomes dirty before the designated laundering time, it all gets changed to an alternative matching set. In the case of the sharing bedroom, both sets of linen are matching to each other and to each set in case one set has to go in midweek but the other set doesn't, I must stress, that they are merely coordinating, not identical (though, that would be good....maybe i'll pop down to matalan this afternoon). My bed has a couple of sets of linen which are all matching with each other and the room, I also have a contrasting throw which matches with all sets.
Towels are coordinated with bathroon type. The children's bathroom (blue) has blue towels and blue mats and pedestal mats etc; our bathroom (cream) likewise; cloakroom (red) likewise still.
The Kitchen has all matching/coordinating teatowels, hand towels and dishcloths, curtains and oven gloves largely because these are often visible to the naked eye and 'on show' to visitors.
With the exception of the children's bedrooms which are decorated in a more personalised style to their owner, the whole house is coordinated with itself also. Downstairs; all the flooring is the same; upstairs likewise. The walls are all the same colour and rooms are differentiated via furniture (obviously) plants and softfurnishings each room being different but coordinating/contrasting. I like the sense of continuity and at the end of the day with matching things, everywhere looks tidier than if it doesn't match.
sorry, to be in the 'control freak' camp. I don't think I'm controlling, I just like things to be matching....
