ya'll will laugh at me, but when Dh and I had our first place adn I was less-than-crafty, I bought a beautiful set of sheets that I loved, and used fusible hem tape (the stuff that you iron on to hold up a hem when you don't know how to sew) to put them together to make a duvet cover for our queen down comforter. I put the tap on three edges, and left the top edge open so that I could slip it in, and then sewed buttons at the top, and matching ribbon across fromt eh bottons (on teh other flap) so they'd have a place to close. You could sew on ribbon ties too. It was super easy, super cheap, and now, 8 years later, I've STILL got that duvet cover, LOL!! Dh laughs every time I put it on the bed, but hey! It's still working and looks great!
