Bought my first pure white totally too expensive kingsize duvet.It cost me far more than i would normally pay to match the lovely bedroom dh just renovated for me.It takes me about 45 mins to iron the bl*y thing and looks like its never seen an iron by morning.All the previous duvets i bought were a lot cheaper, probably polyester or something, and at least stayed somewhat neat looking for a few days.What am i doing wrong ? Any miracle ideas ?
