Whether you’re a DIY enthusiast or just looking for the best pillow for your home, this guide will cover everything you need to know about knife edge pillows, including how to make one yourself.

What is a Knife Edge Pillow?

A knife edge pillow is a pillow with a straightforward, seamless edge where two fabric panels are sewn together without any decorative elements like piping or cording.

This creates a smooth, streamlined look that works well in various home decor styles, from minimalist to rustic.

Benefits of a Knife Edge Pillow:

  • Sleek and modern design that fits effortlessly into any home aesthetic.

  • Easy to sew and maintain, making it an excellent DIY project.

  • More fabric flexibility, allowing for a range of textures and patterns.

  • Soft and plush appearance, as it doesn’t have a stiff border or decorative trim.

Unlike box-edge pillows, which have a structured, three-dimensional shape, knife edge pillows offer a more relaxed and inviting look, making them ideal for sofas, beds, and lounge areas.

How to Make a Knife Edge Pillow

Creating your own DIY knife edge pillow is a rewarding and straightforward project. Follow these steps to craft a high-quality, stylish pillow for your home.

Materials Needed:

  • Fabric of your choice (cotton, linen, or velvet work well)

  • Pillow insert (size of your choice)

  • Matching thread

  • Fabric scissors

  • Pins or fabric clips

  • Sewing machine (or needle if hand-sewing)

  • Measuring tape

  • Iron for pressing seams

Step-by-Step Instructions:

  1. Measure and Cut the Fabric

    • Cut two identical fabric squares or rectangles, adding a 1-inch seam allowance on all sides.

    • If using patterned fabric, ensure the pattern aligns correctly for a cohesive look.

  2. Pin the Fabric Together

    • Place the fabric panels right sides together and pin around the edges, leaving a small opening for turning the pillow inside out.

    • Ensure even pinning to maintain a uniform edge when sewing.

  3. Sew the Pillow Cover

    • Use a straight stitch around the edges, maintaining a ½-inch seam allowance.

    • Reinforce corners by stitching backward and forward to prevent unraveling and strengthen the structure.

  4. Turn the Pillow Right Side Out

    • Trim excess fabric at the corners for a neater finish and sharper edges.

    • Use a blunt tool (like a chopstick or knitting needle) to push out corners for a clean edge.

    • Press the seams with an iron to create a polished look.

  5. Insert the Pillow Filling

    • Carefully insert your pillow form or stuffing, ensuring even distribution for a well-balanced shape.

    • Fluff the filling as needed to achieve the desired firmness.

  6. Close the Opening

    • Hand-sew the opening using a hidden ladder stitch for a seamless finish.

    • Ensure tight, even stitches to prevent filling from escaping and maintain durability.

Pairing a knife edge pillow with a Puffy Lux Mattress adds an extra layer of elegance and comfort, ensuring your bedroom looks as stylish as it feels cozy.

How to Make a Knife Edge Pillow with Zipper

A zippered knife edge pillow offers the same seamless look while allowing for easy removal and cleaning. Here’s how to incorporate a zipper into your pillow design.

Additional Materials:

  • Invisible or standard zipper (same width as pillow edge)

  • Zipper foot attachment for sewing machine

Steps to Add a Zipper:

  1. Prepare the Fabric

    • Cut and align the fabric pieces, ensuring an extra inch of fabric along the side where the zipper will be attached.
  2. Attach the Zipper

    • Pin the zipper face down along one fabric edge.

    • Use a zipper foot to sew as close as possible to the zipper teeth.

    • Repeat on the other fabric panel, ensuring proper alignment.

  3. Secure the Zipper in Place

    • Topstitch along the edge of the zipper for durability and a clean look.

    • Open and close the zipper a few times to ensure smooth operation.

  4. Sew the Remaining Edges

    • Once the zipper is attached, sew the remaining three sides of the pillow.

    • Leave the zipper slightly open before sewing so you can turn the pillow right side out easily.

  5. Insert the Pillow and Zip Closed

    • After turning the pillow right side out, insert the pillow form and zip it closed.

    • Smooth out any wrinkles for a crisp, professional finish.

Choosing the Right Fabric and Fill

The choice of fabric and filling affects both the look and feel of your knife edge pillow. Consider the following options:

Best Fabric Options:

  • Cotton: Lightweight and breathable, ideal for casual settings.

  • Linen: Durable and elegant with a textured look.

  • Velvet: Luxurious and plush for a sophisticated feel.

  • Faux Fur: Adds texture and warmth to the design, making it an eye-catching addition to any space.

  • Microfiber: Soft, wrinkle-resistant, and easy to clean, making it perfect for high-traffic areas or homes with pets.

Fill Options:

  • Down or Feather: Soft and moldable but may require fluffing to maintain shape.

  • Polyester Fiberfill: Budget-friendly and retains shape well, making it a durable choice.

  • Memory Foam: Provides firm support and contours to the body, offering excellent neck and head comfort.

  • Buckwheat Hulls: Naturally moldable and breathable, providing an eco-friendly filling alternative.

Pairing a well-filled knife edge pillow with a Puffy Royal Mattress enhances relaxation by providing additional support and plush comfort.

Conclusion

A knife edge pillow is a stylish and versatile choice for any home. Whether you prefer a simple hand-sewn pillow or a zippered version for convenience, this pillow style is an easy DIY project that can elevate your living space.

With the right fabric, fill, and stitching technique, you can create a beautiful and functional pillow that adds both comfort and elegance to your home decor.
