Exactly that, really. I have a new duvet cover I like and I'm not sure what colour to go for for the sheet and bottom pillow cases.
It's a dark-ish blue with plants/berries on it (red, brown, green, white).
I was thinking of matching the green for a nice contrast, but sometimes I think that only works when the room is super tidy and presentable, as otherwise the contrast can look messy and cluttered.
Boring topic, perhaps! Does anyone have any views on this?
