Non plain sheets for my bed, something patterned or printed

[onetiredUTTERLYTERRIFYINGmummy]

I rented a house a couple of years ago & bought a lovely duvet set for my double bed. The reason I remember it was that the sheet (the sheet that goes under the pillows & duvet) was printed, it wasn't a plain colour like most of them seem to be. It was designed by someone but I can't remember the name.

I've now moved into a new house & have a super king size bed & I'm after a new bed set but with a patterned sheet as I only have plain white at the minute.

I can't find one & I can't remember the designer to google them. Any ideas?
