How to Add a Buttonhole After Finishing Your Knitted Project

We’ve all been there: you finish knitting a sweater, cardigan, or other project, only to realize that you forgot to add buttonholes. Don't worry—it’s not too late! Adding buttonholes after completing your knitting is easier than you might think. In this guide, we’ll walk you through a simple, effective technique to create neat, functional buttonholes in your finished project.

Why Add Buttonholes After Knitting?

Sometimes, design changes or little oversights happen during the knitting process. Maybe you decided to add buttons after seeing the finished piece, or you realized the placement wasn’t quite right. Whatever the reason, you don’t have to rip out your hard work—this method allows you to adapt and customize your project even after it’s bound off.

• Your finished knitted piece
• Scissors
• A tapestry needle
• Matching yarn (or contrasting yarn if you want the buttonhole to stand out)

Step-by-Step Guide to Creating a Buttonhole

1. Choose the Placement

Lay your project flat and decide where the buttonholes should go. Use pins or stitch markers to mark the spots. Ensure they are evenly spaced, especially for a row of buttons on a cardigan.

2. Open the Stitch

Using sharp scissors, carefully snip one stitch at the buttonhole's location. Be sure to cut in the middle of the stitch, not near the edge, to avoid unraveling your fabric.

3. Unravel the Stitch

Pull the cut stitch downward (for a horizontal buttonhole) or sideways (for a vertical buttonhole) to create an opening of the desired size. Adjust based on the button's diameter.

Securing the Buttonhole

Once you’ve created the opening, you’ll need to stabilize it to prevent fraying or distortion. Here’s how:

1. Reinforce the Edges

Thread a tapestry needle with your yarn and use a whipstitch or blanket stitch to secure the raw edges of the buttonhole. Work neatly to ensure durability and an attractive finish.

2. Test the Button

Slide the button through the hole to confirm the size is correct. If it’s too tight, carefully unravel another row of stitches. If it’s too loose, add extra reinforcement with your stitches.

Pro Tip: Match the Buttonhole Style to Your Project

For lightweight projects, use fine yarn to avoid bulky edges. For thicker knits, choose sturdy yarn to ensure the buttonhole holds up over time.

Adaptability Is Key

Knitting is as much about creativity as it is about technique. Adding buttonholes after finishing your project is a great way to stay flexible and customize your creations. Whether it’s a last-minute adjustment or a planned design feature, this method ensures your projects meet your vision.
