How To Thwart King-Size Blanket Thief? -- Good Questions

Pin it Q: My beloved spouse is a huge quilt thief. With our previous bed, we coped with this by simply using a king-size quilt on a queen-size bed. Now that we have a king-size bed, what do we do? Does anyone make huge duvets or quilts? Or... I know sometimes in Europe they just put two twin-size duvets on a king-size bed--but how do you make a bed that way and make it look neat? -Sent by Liz
