How to Stitch A Duvet CoverFinding an attractive duvet cover that complements the decor of a room and is not too costly can be a challenge. Making a cover is not difficult for someone with a sewing machine and even rudimentary sewing skills.Measure the duvet and add about four inches to top, bottom and sides so suitable seams and closure can be created. The finished cover should be the same size as the duvet or slightly larger for best appearance.A cover can be made from fabric purchased from a store or from two flat sheets. White sales will yield good prices on sheets, but buy those with a good thread count. The avid bargain hunter can find quality and very inexpensive sheets at a resale store like Goodwill. Choose sheets or fabric in a color and style that will work with the room.It is also possible to create a unique design by purchasing plain fabric or sheets and using permanent markers that are alcohol-based to draw a design that will coordinate with the room. Experiment first to find a design that will be pleasing. Outline it with markers. Leaving about one fourth of an inch between lines, fill in spaces as desired.On a dry day, take the fabric outdoors. Wear old clothes because this process can stain them. Put 70 percent rubbing alcohol in a spray bottle, and wet the fabric. The colors will run together and blend.Allow the fabric to air dry, which will happen pretty quickly. Bring it indoors and iron it at the setting for cotton blends. After this, it should be laundered with gentle detergent such as Delicare. Dry in the dryer and press if needed.Put the two pieces together with right sides in, then stitch together with a half-in seam, leaving one end open. Add a second seam for strength. Trim the seam to a fourth of an inch. Clip corners and turn. Or make French seams. Sew in a zipper of the proper length on the open end.The new duvet cover will be easy to remove for occasional laundering. If desired, use a button closure with buttonholes instead. This takes more time and will be less convenient, but the duvet cover does not need laundering too often if sheets are used with it.
