What You’ll Need: Your Outdoor Cushion Cover Toolkit

Gathering your supplies is the first exciting step! Having everything ready before you start makes the sewing process smooth and enjoyable. Here’s a list of essentials for sewing cushion covers for outdoor furniture:

Essential Sewing Supplies:

Sewing Machine: Any functional sewing machine will do. If you have one for basic repairs, it’s perfect for this.
Thread: Use a strong, UV-resistant polyester thread. This is crucial for outdoor use as it won’t degrade in the sun.
Sharp Fabric Scissors: A dedicated pair for fabric keeps your cuts clean and precise.
Measuring Tape: A flexible tape measure is essential for accurate measurements of your cushions.
Fabric Marker or Chalk: For marking your cut lines on the fabric.
Pins: To hold your fabric pieces together before sewing.
Zipper or Velcro: For closing your cushion covers. Zippers are more durable and professional-looking for outdoor furniture. (Consider a heavy-duty outdoor zipper for best results).
Sewing Machine Needles: Use a universal needle or a needle specifically designed for outdoor fabrics if available.

Fabric Choices for Outdoor Cushion Covers:

Choosing the right fabric is paramount for success. You need materials that can withstand sun, rain, and general outdoor use. Look for fabrics that are:

UV Resistant: Prevents fading and degradation from sunlight.
Water Repellent/Resistant: Encourages water to bead up and roll off, drying faster.
Mildew Resistant: Prevents the growth of mold and mildew, which is common in humid environments.
Durable: Can withstand friction and general use.

Some popular and effective choices include:

Acrylic Fabrics (e.g., Sunbrella): Often considered the gold standard for outdoor performance. They are incredibly durable, fade-resistant, water-repellent, and breathable.
Polyester Fabrics with Outdoor Treatments: Many polyester fabrics are treated to be water-repellent and UV-resistant. Look for descriptions like “outdoor polyester” or “treated polyester.”
Vinyon/Vinyl Fabrics: Highly waterproof and easy to clean, but can sometimes feel stiff or get hot in direct sun.
Olefin Fabrics: Similar to acrylics in performance, offering good durability, fade resistance, and moisture-wicking properties.

You can often find great outdoor fabric selections at your local fabric store or online retailers specializing in home décor or outdoor goods. FabricLink.com offers a helpful guide on understanding different fabric types and their properties, which can be a great resource when making your selection.

Step-by-Step Guide: Sewing Your Own Outdoor Cushion Covers

Let’s get sewing! This guide will walk you through creating a simple envelope-style cover, which is great for beginners. If your cushion is particularly thick or has rounded corners, the process might vary slightly, but the core principles remain the same.

Step 1: Measure Your Cushion Accurately

Precision here saves frustration later! You need to measure the width, height, and depth of your cushion. Don’t guess – use your measuring tape.

Width (W): Measure across the top surface of the cushion from side seam to side seam.
Height (H): Measure from the top surface down to the bottom edge of the cushion.
Depth (D): This is the thickness of your cushion. Measure from the front edge to the back edge.

So, for a cushion that is 20 inches wide, 20 inches tall, and 4 inches deep, your key measurements are W=20″, H=20″, and D=4″.

Step 2: Calculate Your Fabric Piece Sizes

We’ll be cutting two main pieces for the front and back of the cushion. These will be larger than your cushion to allow for seams and the envelope closure.

For the Main Cushion Panel(s):

Width Needed: Cushion Width (W) + Cushion Depth (D) x 2 + Seam Allowance (1 inch total = 0.5 inch per side)
Height Needed: Cushion Height (H) + Cushion Depth (D) + Seam Allowance (1 inch total = 0.5 inch per side)

Using our example cushion (W=20″, H=20″, D=4″):

Width Needed: 20″ + (4″ x 2) + 1″ = 20″ + 8″ + 1″ = 29 inches
Height Needed: 20″ + 4″ + 1″ = 25 inches

So, you’ll need two pieces of fabric, each measuring 29 inches wide by 25 inches tall.

Step 3: Prepare the Envelope Closure (for the Back Panel)

This is where the magic happens to create the opening for inserting the cushion. We’ll create an overlap on one of the main fabric panels (this will be your back panel).

Take one of your main fabric panels (29″ x 25″). This will be the back panel. Along one of the long edges (the 29-inch side that will be the top edge of your cushion), you need to create the envelope opening.

Fold and Press: On the top edge of this panel, fold over ½ inch of fabric towards the wrong side (the side less attractive). Press this fold firmly with your iron.
Fold Again: Fold over another 3 inches of fabric towards the wrong side. Press this fold firmly. This creates a wide hem, which will be the overlapping flap for your envelope closure.
Stitch the Hem: Sew along the folded edge of the 3-inch fold, close to the raw edge. This secures the hem. Use a strong stitch and backstitch at the beginning and end.

Note: You’ll do this to only ONE of the long edges of ONE of the two main panels.

Now, you should have two fabric panels. One is a simple rectangle (29″ x 25″). The other is the same size but has a wide, finished hem along one of its 29-inch edges.

Step 4: Pin Your Fabric Pieces Together

Time to assemble the cover! Lay your unhemmed main fabric panel (the front panel) right side up on a flat surface.

Place the Back Panel: Lay the second fabric panel (the one with the hemmed enclosure) on top of the first panel. Ensure the right sides of both fabrics are facing each other.
Align the Edges: The raw edges of both fabric panels should align perfectly. The completed hemmed flap of the back panel should be positioned so it overlaps the other panel, creating the envelope opening. Imagine the cushion is inside – this flap needs to cover the top edge.
Pin Everything: Pin all four sides securely through both layers of fabric. Pay extra attention to the corners and the edges of the envelope flap.

Step 5: Sew the Cushion Cover

Now, let’s stitch it all together!

Stitch Around All Four Sides: Using your sewing machine and your chosen thread, stitch around all four edges of the pinned fabric. Use a ½-inch seam allowance. This means sewing ½ inch in from the raw edge.
Reinforce Corners: For extra durability, you can sew back and forth a few times at each corner to reinforce them.
Beginner Tip: If you’re new to sewing, sew slowly and guide the fabric. Don’t pull or push it through the machine; let the feed dogs do the work.

Step 6: Trim and Finish Seams (Optional but Recommended)

For a tidier finish and to reduce bulk, you can:

Trim Corners: Clip the fabric diagonally across each of the four corners, being careful not to cut through your stitching. This helps the corners lie flatter when turned right side out.
Finish Seams: If your fabric tends to fray, you can finish the raw edges of the seams. You can do this with a zigzag stitch along the raw edge of each seam allowance, or use pinking shears if you have them. Some sewing machines also have a serger function or overlock stitch that works beautifully.

Step 7: Turn and Insert Your Cushion

You’re almost there!

Turn Right Side Out: Carefully reach through the envelope opening and pull the fabric right side out. Use your fingers or a point-turner tool to push out the corners neatly.
Insert Cushion: Gently slide your existing cushion into the newly made cover through the envelope opening. The overlapping hemmed flap will keep it securely inside.
Admire Your Work! Place the newly covered cushion back on your outdoor furniture.

Advanced Techniques & Considerations

Once you’ve mastered the basic envelope cover, you might want to explore other options or add some extra flair. Here are a few ideas:

Adding Piping (Welting Cord)

Piping adds a decorative, finished edge that defines the shape of your cushion beautifully. It’s a bit more involved but adds a professional touch.

What you need: Welting cord (a cording with a fabric flange), matching fabric for the piping.
How it works: You’ll create strips of fabric to wrap around the welting cord, then sew this “homemade piping” to the edges of your cushion panels before you join the front and back panels together.
Resources: Many sewing tutorials online demonstrate how to make and attach piping. A reliable source like Joann’s sewing techniques section can offer visual guides here.

Using Zippers for a Tighter Fit

While the envelope closure is easy and effective, a zipper offers a very neat and secure finish, especially for cushions that are frequently moved or have very tight inserts.

Placement: Zippers are typically installed along one of the cushion’s seams, often the back or a side.
Fabric Tape: For outdoor furniture, consider a heavy-duty outdoor zipper. Some zippers come with fabric tape that is specifically designed to withstand outdoor elements.
Installation: This involves sewing the zipper into one of your fabric panels before joining the front and back. It requires a bit of precision, but many sewing machines come with zipper feet that make the process much easier.

Welted Corners vs. Boxed Corners

The method described above creates a relatively simple cover. For a more structured look, you can create “boxed corners,” which resemble a fabric box with defined edges. This involves sewing side panels to your front and back panels, creating a 3D effect.

Boxed Corners: Imagine sewing a skirt onto the top panel. This requires measuring and cutting four side panels in addition to your top and bottom.
Corner Style: You can have ‘pleated’ corners or ‘mitered’ corners for a tailored look.

Waterproofing and Finishing Sprays

Even with water-repellent fabrics, you can add an extra layer of protection. After sewing your covers, consider applying a fabric waterproofing spray designed for outdoor use. Always test the spray on a small scrap of your fabric first to ensure it doesn’t alter the color or texture negatively.

Caring for Your New Outdoor Cushion Covers

You’ve put in the effort to create beautiful, durable cushion covers – now let’s make sure they last! Proper care will keep them looking fantastic season after season.

Regular Cleaning:

Spot Clean: For minor spills or dirt, use a mild soap and water solution with a soft brush or sponge. Rinse thoroughly and allow to air dry completely.
Deep Clean: For more significant dirt or mildew, you can often remove the covers and wash them in a washing machine on a gentle cycle with cool water and a mild detergent. Always check the fabric manufacturer’s care instructions first!
Drying: Never put outdoor fabric cushion covers in a dryer, as the heat can damage the fabric’s water-repellent coating and fibers. Always air dry them completely, preferably in the sun if possible, as sunlight can help kill mildew spores.

Protecting from the Elements:

Bring Them In: During extended periods of non-use, especially during harsh weather (heavy rain, snow, or prolonged sun exposure during off-seasons), store your cushion covers indoors in a dry, well-ventilated area.
Use a Cover: If you don’t have space to store them indoors, consider using a breathable outdoor furniture cover to protect them further.
Allow Airflow: Even when cushions are on the furniture, try to allow for some airflow to prevent moisture buildup, which can lead to mildew.

Following these simple care tips will dramatically extend the life of your handmade outdoor cushion covers, keeping your outdoor space looking inviting and comfortable for years to come.

Common Questions About Sewing Outdoor Cushion Covers

Q1: What is the best type of fabric for outdoor cushion covers?

The best fabrics are typically acrylics (like Sunbrella), treated polyesters, or olefin fabrics. These are chosen for their resistance to UV rays, water, mildew, and general durability.

Q2: Do I need a special sewing machine for outdoor fabrics?

No, a standard home sewing machine is usually sufficient. However, ensure you have sharp needles and strong, UV-resistant polyester thread. Heavy-duty outdoor fabrics might require a more robust machine, but for average cushions, a standard model works well.

Q3: How much fabric do I need?

This depends on the size of your cushions. You’ll need enough to make two main panels, plus any additional pieces for zippers, piping, or boxed corners. Always buy a little extra to account for mistakes or shrinkage.

Q4: What is an envelope closure, and why is it good for cushion covers?

An envelope closure is a simple overlap in the fabric that allows you to insert
