A Basic Sewing Machine Cover Protects Against Dust and Damage
A sewing machine cover is a fabric shell that sits over your machine when you are not using it. It keeps dust, lint, and pet hair off the feed dogs, tension discs, and bobbin area—places where debris causes jams and thread breaks. You can buy a ready-made cover, but making one takes an afternoon and costs only the price of fabric, and you can size it exactly to your machine.
The simplest cover is a rectangular box with an open bottom. You sew four fabric panels together, add a top flap, and slip it over your machine like a pillowcase. No zippers, no elastic, no complicated seams. If your machine is 15 inches wide and 8 inches deep, your cover will be too.
Key Takeaways
- Measure your machine's width, depth, and height, then add 1 inch to each dimension to account for seam allowance and a loose fit.
- Cut four fabric panels for the sides and one rectangle for the top, using medium-weight cotton or quilting fabric that will not stretch.
- Sew the four side panels together at the corners, then attach the top panel, leaving the bottom open so you can slide the cover on and off.
- Finish the raw edges with a zigzag stitch or bias tape to prevent fraying and make the cover last longer.
- A cover with a drawstring casing at the bottom keeps it in place and prevents dust from blowing underneath while your machine sits on the table.
Measure Your Machine and Plan Your Fabric Layout
Start by measuring your sewing machine in three directions: width (side to side), depth (front to back), and height (bottom to top of the presser foot or thread guides). Write these numbers down. A typical home machine is about 15 inches wide, 8 inches deep, and 12 inches tall, but yours may differ.
Add 1 inch to the width and depth measurements. This extra space lets the cover slip on without binding and accounts for the seam allowance where panels meet. Do not add extra height—measure to the highest point you want the cover to reach, usually just above the presser foot or thread guides.
Choose a medium-weight, non-stretch fabric. Cotton quilting fabric, canvas, or home-décor cotton work well. Avoid knits, thin cotton, or anything slippery—they will not hold their shape and the cover will slide around. You will need enough fabric to cut four side panels and one top panel. A piece 45 inches wide by 1 yard long is usually enough for a standard machine.
Cut and Prepare Your Fabric Panels
Lay your fabric on a flat surface and use a ruler and rotary cutter or scissors to cut straight edges. You need five pieces:
- Two panels for the front and back: each (width + 1 inch) by (height) inches.
- Two panels for the sides: each (depth + 1 inch) by (height) inches.
- One top panel: (width + 1 inch) by (depth + 1 inch) inches.
For example, if your machine is 15 inches wide, 8 inches deep, and 12 inches tall, cut two front/back panels 16 by 12 inches, two side panels 9 by 12 inches, and one top panel 16 by 9 inches.
Before you sew, press all five pieces with an iron on a medium setting. This removes wrinkles and makes the seams lie flat. It also prevents the fabric from puckering when you sew.
Sew the Four Side Panels Together
Place two panels with their right sides facing each other (the pretty sides touching). Pin along one edge, then sew a straight seam 1/2 inch from the edge using a thread color that matches your fabric. Backstitch at the start and end to lock the seam. Remove the pins as you go.
Open the two panels so the seam is on the inside and press it flat with your iron. Repeat this process to attach the remaining two panels, building a tube shape. You should now have four panels sewn into a box with no top or bottom.
At each corner where two seams meet, you will see a small ridge of fabric. Trim this down to 1/4 inch and zigzag stitch along the cut edge to prevent fraying. This step, called finishing the seam, keeps the inside of your cover neat and prevents threads from coming loose over time.
Attach the Top Panel and Finish the Edges
Place your fabric box right-side out on the table. Lay the top panel on top, right side down (so the pretty side faces the inside of the box). Pin all four edges, then sew around the perimeter 1/2 inch from the edge. Backstitch at the corners. When you are done, flip the whole cover right-side out through the open bottom—the top panel is now attached and facing outward.
Press the seams flat with your iron, paying special attention to the corners. If the corners are bulky, trim the seam allowance to 1/4 inch in the corner area before you flip it right-side out.
Finish the raw edges at the open bottom by folding them inward 1/2 inch and pressing, then sewing a straight stitch close to the fold. Alternatively, cut 1-inch-wide bias tape, fold it over the raw edge, and sew it down—this looks more polished and is more durable.
Add a Drawstring Casing to Keep the Cover find
A drawstring at the bottom prevents the cover from shifting and stops dust from creeping underneath. Fold the bottom edge inward 1 inch and press. Sew a straight stitch 3/4 inch from the fold, creating a tunnel. Leave a 1-inch gap in one spot so you can thread the drawstring through.
Cut a piece of cord or thick ribbon about 36 inches long. Thread it through the tunnel using a safety pin or bodkin (a blunt needle with a large eye). Tie the ends together so the drawstring forms a loop. When you pull the loop, the bottom of the cover gathers and cinches around your machine.
If you do not want a drawstring, straightforward leave the bottom open. The cover will still protect the top and sides of your machine, and you can pull it off quickly when you want to sew.
Customize Your Cover with Pockets or Handles
Once you have made a basic cover, you can add features that make it more useful. A small pocket sewn to the outside holds spare bobbins, needles, or a seam ripper. Cut a rectangle 4 by 5 inches, fold the top edge down 1/2 inch and sew it, then pin the pocket to the front panel and sew three sides, leaving the top open.
Handles make it easier to carry the cover if you transport your machine. Cut two strips of fabric 2 inches wide and 8 inches long. Fold each strip in half lengthwise, press, and sew close to the open edge. Pin the ends to the top panel on either side and sew them down securely before you attach the top panel to the box.
You can also add a decorative trim or binding around the top edge, embroider your initials on the front, or use patterned fabric that matches your sewing room. The cover is yours to design.
Frequently Asked Questions
What fabric should I use if I want the cover to be waterproof?
Use cotton canvas or home-décor fabric with a water-resistant coating, or sew two layers of regular cotton with a layer of oilcloth or laminated fabric sandwiched between them. Laminated fabric is slippery to sew, so use a walking foot if your machine has one, and go slowly. Avoid vinyl or plastic sheeting—they trap moisture and can damage the machine.
Can I make a cover for a serger or overlock machine?
Yes, the same method works. Measure your serger's width, depth, and height, then follow the same steps. Sergers are often taller and narrower than sewing machines, so your proportions will be different, but the construction is identical. Make sure the cover does not press down on the thread guides or tension discs when it is in place.
How do I keep the cover from sliding off the machine?
A drawstring casing at the bottom is the most reliable method. If you do not want a drawstring, sew elastic into the bottom hem instead—cut a piece of 1/2-inch-wide elastic about 2 inches shorter than the perimeter of your machine's base, insert it into the hem as you sew, and it will hold the cover snug. Test the fit before you sew it permanently.
What if my machine has a large presser foot or attachments that stick up?
Measure to the highest point, including any attachments you leave on the machine. If you use a walking foot or quilting foot that adds height, measure with it in place. The cover should slip on without forcing—if it is too tight, add another inch to the height measurement and re-cut the side panels.
