What You Need to Know Before You Start

A slipcover is a fitted fabric shell that wraps around a chair frame. Unlike reupholstering, which replaces the original fabric permanently, a slipcover sits on top and can be removed, washed, and replaced. You can make one without taking the chair apart, though the fit will be looser than a professional reupholster's work. A basic slipcover takes 8 to 16 hours of sewing time spread across a few days, depending on your speed and the chair's shape.

The hardest part is measuring and cutting accurately. The sewing itself — mostly straight seams and straightforward hems — is within reach of anyone who can thread a machine and sew a straight line. You will need a sewing machine, fabric, thread, scissors, pins, and measuring tools. Fabric choice matters: medium-weight cotton, linen blends, or canvas hold their shape better than thin fabrics and are easier to work with than stretchy knits.

Key Takeaways

  • Measure your chair in sections (seat, back, arms, skirt) and add 2 to 3 inches to each measurement for seam allowance and tucking.
  • Cut pattern pieces from muslin first, fit them to the chair, and mark seams with pins before cutting your final fabric.
  • Sew the main pieces together with straight seams, then attach the skirt (the bottom ruffle) and hem the edges.
  • A slipcover with a fitted seat and loose back is simpler than a fully tailored cover and still looks polished.
  • Prewash your fabric before cutting to prevent shrinkage after the slipcover is finished.

Measuring Your Chair Correctly

Measure the chair in five separate sections: the seat, the inside back, the outside back, the arms, and the skirt (the distance from the seat to the floor). For each section, measure the width, height, and depth. Write these numbers down — do not rely on memory. Measure twice; the second time will catch mistakes.

Add 2 to 3 inches to every measurement for seam allowance (the fabric that gets sewn into the seams) and tucking (extra fabric that tucks into the crevices where the seat meets the back and arms). This extra fabric is what keeps the slipcover from sliding around. If your chair has a curved back or rolled arms, add an extra inch or two to those sections because curves waste fabric.

Sketch a straightforward diagram of your chair and write the measurements directly on it. Include the grain direction of the fabric you plan to use — most fabrics look better when the pattern runs the same direction on all pieces. This diagram becomes your cutting guide.

Making a Pattern from Muslin

Muslin is an inexpensive, plain-weave cotton. Using it to test your pattern before cutting expensive fabric saves money and frustration. Cut muslin pieces slightly larger than your measurements — about 4 inches extra on all sides. Pin the muslin to the chair in the order you will sew: seat first, then inside back, then arms, then outside back.

Smooth each piece as you pin it, removing wrinkles and excess fabric. Mark the seam lines with a fabric pen or tailor's chalk. Where two pieces meet (seat to back, seat to arm), fold the fabric and crease it to show exactly where the seam should go. Unpin one section at a time, lay it flat, and cut along your marked lines. You now have a custom pattern that fits your specific chair.

Try the muslin slipcover on the chair. It should be snug but not tight. If it pulls or gaps, adjust the pattern pieces before moving to your final fabric. This step takes an hour but prevents cutting mistakes in fabric you paid for.

Cutting and Preparing Your Fabric

Prewash your fabric in warm water and dry it on low heat. This prevents shrinkage after the slipcover is finished and ready to use. Lay the fabric on a flat surface and arrange your muslin pattern pieces on top, following the grain direction you marked on your diagram. Pin the pattern to the fabric and cut around each piece with sharp scissors. Mark the seam lines on the fabric with tailor's chalk or a fabric pen.

Cut a separate piece for the skirt — the ruffle that hangs from the seat to the floor. The skirt should be as long as your measurement from seat to floor plus 1 inch for the hem, and as wide as the perimeter of the seat (the distance around it) plus 4 inches for seams. If your fabric is not wide enough, cut two or three strips and sew them together end-to-end to make one long piece.

Sewing the Main Pieces Together

Start with the seat. Place the seat piece right-side up on your work surface. Lay the inside back piece on top of it, right sides facing each other (the pretty sides touching). Pin along the seam line where they meet. Sew with a straight stitch, using a 1/2-inch seam allowance. Backstitch at the beginning and end to lock the thread.

Attach the arms next. Pin one arm piece to the side of the seat, right sides together. Sew along the seam line. Repeat on the other side. Then attach the outside back piece, pinning it to the inside back and sewing along the top edge. Press each seam flat with an iron as you finish it — this makes the next seam easier to sew straight.

Try the slipcover on the chair. It should fit snugly around the seat and back with no gaps at the seams. If a seam pulls or bunches, you can adjust it by taking it apart, moving the seam line slightly, and resewing. This is normal and expected.

Attaching the Skirt and Hemming

The skirt is the fabric that hangs from the seat to the floor. Fold the top edge of the skirt piece 1/2 inch toward the wrong side (the back) and press it flat. Pin this folded edge to the bottom edge of the seat piece, right sides together. The skirt will bunch up because it is longer than the seat perimeter — this creates the gathered or pleated look. Sew along the pinned edge with a straight stitch.

Fold the bottom edge of the skirt up 1 inch toward the wrong side and press. Fold it up another 1 inch and press again. This double fold hides the raw edge and prevents fraying. Pin the hem in place and sew it with a straight stitch, staying close to the inner fold. Use a thread color that matches your fabric so the stitches are less visible.

Try the finished slipcover on the chair one more time. The skirt should touch the floor or sit 1/2 inch above it. If it is too long, trim the bottom edge and re-hem it. If it is too short, you will need to add a strip of fabric to the bottom — this is rare if you measured correctly.

Finishing Touches and Care

Trim any loose threads and press the entire slipcover with an iron on a medium setting. If your fabric is delicate, use a pressing cloth (a thin piece of cotton) between the iron and the slipcover to prevent shine marks. Wash the slipcover in cool water on a gentle cycle and dry it on low heat or hang it to air-dry. This prevents shrinkage and keeps the fabric soft.

Store the slipcover in a clean, dry place when not in use. If it wrinkles, you can press it again or hang it in a steamy bathroom to let the wrinkles fall out naturally. A well-made slipcover lasts 3 to 5 years with regular washing, depending on fabric quality and how often you use the chair.

Frequently Asked Questions

What if my chair has curved or rolled arms?

Curved arms are harder to fit smoothly. Add an extra 2 inches to your arm measurements and plan to make small tucks or darts (small triangular seams) where the fabric bunches. Mark these tucks on your muslin pattern before cutting your final fabric. You can also use bias tape (fabric cut on the diagonal) to bind curved edges neatly.

Can I use a stretchy fabric like jersey or knit?

Stretchy fabrics are difficult for beginners because they shift as you sew and do not hold their shape well. Stick with medium-weight woven fabrics like cotton, linen, or canvas. These are forgiving, straightforward to sew, and look professional when finished.

How much fabric do I need to buy?

Add up the width and length of all your pattern pieces, then add 20 percent extra for mistakes and shrinkage. Most chairs need 4 to 6 yards of 54-inch-wide fabric. Bring your measurements to a fabric store and ask the staff to estimate — they see this project often and can give you an accurate number.

What if I make a mistake while sewing?

Use a seam ripper to cut the stitches and pull them out. Repin the pieces and sew again. This is normal and happens to experienced sewers too. The only real mistake is sewing too fast to notice problems — slow down and check your work as you go.

Do I need a special presser foot for thick seams?

A standard presser foot works for most slipcover fabrics. If you are sewing through four layers of fabric at a seam (like where the skirt meets the seat), go slowly and let the machine do the work. If the needle struggles, you can use a walking foot, which feeds thick layers evenly, but it is not required for a basic slipcover.
