This assumes I want all matchymatchy sheets on my bed. I prefer my main pillow and my husband's main pillow to look different so we don't get them switched, and I prefer the top and bottom sheets to be from different sets. Tonight my pillow is solid blue, his is white, the fitted sheet is blue stripes, the top sheet is white, and the back pillow is blue paisley. Why have all oboes one week and all violas the next when you can have a symphony every week?
You could always store mixed sets too. Unless you like to choose at the time of making your bed. I have a mix on my bed at the moment but that's because I have a king size just for me and my dogs use the other side.
