We never used a top sheet when duvets (continental quilts as they were called then (and were very expensive - I made my own with a kit)) first came in - a top sheet defeats the object of this lightweight cover moulding itself around your body to keep you warmer.

Oh, and for the OP, apart from for weddings and funerals, I haven't ironed for about 25 years. When I do, it's with a travel iron on a folded towel on a table.
