How to Sew a Slipcover

Remove any loose cushions from the chair or couch. In order to make a custom slipcover, create a pattern made to fit your couch or chair. Begin with one arm and drape it with muslin or old sheets. Pull it snugly against the arm of the chair. Pin along the desired seam lines with T-pins and mark it with a fabric marker.

Repeat the pinning process for the entire piece of furniture. Mark each seam as it is pinned. Pin and mark any darts, pleats and gathers as desired. Larger areas, including the expanse under the cushions, can simply be measured for size. Allow additional seam allowance to tuck at the back and sides of the seat for a more secure fit and to reduce tension.

Cut out your muslin slipcover pattern, allowing for generous seam allowances along the marked lines. Baste together with a long stitch length and try on your sample. Make any fitting changes at this point to ensure a perfect fit before you cut your expensive decorator fabric for your custom slipcover.

Snip the seams apart and use your muslin slipcover pattern to cut the pieces from your decorator fabric. Take the time to match patterns or plaids, especially on any prominent back seams. This will make for a more professional result for your custom slipcover.

Sew your new slipcover with sturdy upholstery thread. Either leave an overlap in the center back or install velcro or a zipper to close. Consider piping or cording the seams for style and durability. Make covers for any pillows or cushions, using either the custom pinning method described here or published sewing instructions.
