Sewing Covers For Outdoor Cushions

Sewing Covers for Outdoor Cushions: A Comprehensive Guide

Outdoor cushions enhance the aesthetic appeal and comfort of patios, decks, and other outdoor living spaces. However, the elements can quickly degrade the fabric, leading to fading, mildew, and general wear and tear. Sewing custom covers for outdoor cushions provides a cost-effective solution for protecting these investments and extending their lifespan. This article provides a comprehensive guide to sewing durable and attractive covers for outdoor cushions, covering fabric selection, measurement techniques, sewing processes, and finishing touches.

Understanding the Importance of Suitable Fabric Selection

The choice of fabric is paramount when sewing covers for outdoor cushions. The fabric must be able to withstand prolonged exposure to sunlight, moisture, and temperature fluctuations. Certain fabrics are inherently more suitable for outdoor use than others, offering varying degrees of resistance to fading, water damage, and mildew growth.

Outdoor fabrics are often treated with water-repellent finishes to prevent moisture from penetrating the fibers. This treatment, however, may diminish over time due to washing and exposure to the elements. Therefore, selecting a fabric with inherent water resistance, coupled with a protective finish, typically offers the best long-term protection for outdoor cushions.

Several popular fabric options for outdoor cushion covers include solution-dyed acrylic, polyester, and olefin. Solution-dyed acrylic fabrics, such as Sunbrella, are renowned for their exceptional colorfastness and resistance to fading. The pigments are integrated into the fiber itself during the manufacturing process, ensuring that the color remains vibrant even after prolonged exposure to sunlight. Polyester fabrics offer good durability and water resistance at a more affordable price point. Olefin fabrics are also known for their resistance to fading and mildew, making them another viable option. Cotton, while comfortable, is generally not recommended for outdoor use unless treated with a water-resistant coating, as it is prone to mildew and fading.

In addition to water resistance and colorfastness, consider the fabric's abrasion resistance. The fabric should be able to withstand regular use and friction without tearing or wearing thin. A higher thread count typically indicates a more durable fabric. It is also advisable to check the fabric's "double rubs" rating, which measures its resistance to abrasion. A rating of 15,000 double rubs or higher is generally considered suitable for outdoor cushions.

Beyond the functional considerations, the aesthetic appeal of the fabric is also important. Consider the color, pattern, and texture of the fabric in relation to the overall design of the outdoor space. Choose a fabric that complements the existing furniture and landscaping. Available options range from solid colors to intricate patterns, providing ample opportunities for customization.

Accurate Measurement and Pattern Creation

Precise measurement and pattern creation are essential for achieving a well-fitting cushion cover. Inaccurate measurements can result in covers that are too tight, too loose, or otherwise ill-fitting. The following steps outline a systematic approach to measuring cushions and creating a pattern.

Begin by measuring the length, width, and thickness (or height) of the cushion. Use a flexible measuring tape to ensure accurate measurements. For irregularly shaped cushions, it is helpful to create a template using paper or cardboard. Lay the cushion on the paper or cardboard and trace its outline. Add seam allowances to the traced outline. A seam allowance of 1/2 inch is generally sufficient for most outdoor fabrics.

For box cushions, which have a rectangular or square shape with vertical side panels, you will need to measure the height of the side panels. These measurements will determine the width of the fabric strip needed to create the side panels. Ensure that the measurements account for seam allowances. For cushions with rounded edges, it is advisable to add extra fabric to account for the curvature. You can then trim the excess fabric after sewing the cover.

When creating the pattern, consider the placement of zippers or other closures. Zippers are commonly used to allow for easy removal and cleaning of the cushion cover. The zipper is typically placed along one of the seams, often at the back of the cushion. Measure the length of the zipper and incorporate this measurement into the pattern. Mark the location of the zipper on the pattern pieces.

To create a professional-looking finish, consider incorporating piping or welting into the cushion cover. Piping adds a decorative touch and helps to reinforce the seams. To incorporate piping, measure the circumference of the cushion and add a seam allowance. Cut a strip of fabric to the desired width for the piping. The width of the fabric strip will depend on the thickness of the piping cord. Enclose the piping cord within the fabric strip and sew along the edge. Attach the piping to the cushion cover during the sewing process.

Once the pattern pieces are created, label each piece clearly to avoid confusion during the sewing process. It is also helpful to create a cutting layout to maximize fabric usage and minimize waste. Arrange the pattern pieces on the fabric to ensure that they fit within the available space, and then pin the pattern pieces securely to the fabric.

Sewing Techniques and Construction Methods

The construction of the cushion cover involves several sewing techniques that contribute to its durability and appearance. Selecting the appropriate stitch type and using a heavy-duty thread are essential for creating a strong and long-lasting cover.

A straight stitch is typically used for most of the seams in a cushion cover. Use a slightly longer stitch length than you would for indoor fabrics. This helps to prevent the stitches from pulling out under stress. It is advisable to reinforce the seams with a double row of stitching, especially in areas that are subject to high stress, such as the corners and zipper areas. A zigzag stitch can be used to finish the raw edges of the fabric, preventing fraying. Alternatively, a serger can be used to overlock the edges for a more professional finish.

When sewing multiple layers of fabric, such as when attaching piping, use a walking foot. A walking foot helps to feed the fabric evenly through the sewing machine, preventing slippage and ensuring a consistent stitch length. Use a heavy-duty thread designed for outdoor use. Polyester or nylon thread is generally recommended, as it is resistant to UV degradation and mildew.

To insert a zipper, use a zipper foot on the sewing machine. The zipper foot allows you to sew close to the zipper teeth without damaging them. Baste the zipper in place before permanently sewing it to the fabric. This helps to ensure that the zipper is properly aligned and that the seams are even. For a concealed zipper, use a specialized zipper foot that allows you to hide the zipper teeth completely.

Begin by sewing the side panels together to form a continuous strip. Then, attach the piping to the top and bottom edges of the side panel strip. Next, attach the top and bottom pieces of the cushion cover to the side panel strip. Ensure that the corners are neatly aligned and that the seams are securely stitched. Leave an opening for the zipper along one of the seams. Insert the zipper into the opening and sew it in place.

Once the cushion cover is completely sewn, turn it right side out and insert the cushion. Check the fit of the cover and make any necessary adjustments. If the cover is too loose, you can take it in at the seams. If the cover is too tight, you may need to add gussets or release the seams slightly. A well-fitting cushion cover should be snug but not overly tight.
