Lining a Hexagon Cardigan and Sewing in a Zipper – A Complete Guide for Crocheters Ready to Level Up

Lining a Hexagon Cardigan and Sewing in a Zipper – A Complete Guide for Crocheters Ready to Level Up

A Reddit user recently shared a dilemma that resonates with many crocheters: “I would like to lift my crochet projects to a next level by trying to sew in a lining and a zipper to a hexagon cardigan. While I am not a crochet beginner, I have never touched a sewing machine and it feels kinda daunting!”

The desire to elevate handmade garments is universal. A well-fitted lining and a professional zipper can transform a cozy cardigan into a polished, wearable piece. But for crocheters who have never touched a sewing machine, the transition can feel overwhelming.

This guide breaks down everything you need to know—from choosing between hand-sewing and machine-sewing, to selecting the right materials, to building the confidence to take your crochet projects to the next level.

1. Why Add a Lining and Zipper to a Crochet Cardigan?

The Reddit user's goal is to “lift” their crochet projects. Adding a lining and zipper does exactly that.

Benefits of a lining:

• Professional finish: Covers the wrong side of your stitches for a clean, polished look

• Comfort: Prevents yarn from catching on clothing underneath

• Durability: Reduces stretching and wear on the crochet fabric

• Structure: Helps the cardigan hold its shape

Benefits of a zipper:

• Clean closure: Creates a smooth, modern front opening

• Versatility: Makes the cardigan more wearable and practical

• Professional look: Elevates handmade items to look store-bought

The Reddit user wants to “lift” their crochet projects, and a lining with a zipper is one of the most effective ways to achieve that.

2. Hand-Sewing vs. Machine-Sewing: Which Should You Choose?

The Reddit user admitted, “I have never touched a sewing machine and it feels kinda daunting!” and said, “I would like to sew by hand for that reason”. This is a common hesitation—but it's worth reconsidering.

The truth: A sewing machine is not something to fear—it's a tool that opens up new creative possibilities. Once you learn the basics, you'll wonder why you waited so long.

3. What Do You Need to Line a Crochet Cardigan?

Before you start, gather the right materials. The Reddit user was open to trying a sewing machine, but unsure where to begin.

Essential supplies:

• Lining fabric: Choose a lightweight, smooth fabric that complements your yarn (e.g., cotton voile, silk charmeuse, or poly lining)

• Zipper: A separating zipper is essential for a cardigan so the front opens completely

• Sewing machine: Optional but highly recommended for a professional finish

• Thread: Match the color to your fabric or zipper

• Pins or clips: To hold everything in place before sewing

• Fabric scissors: For cutting lining and zipper tape

• Measuring tape: To measure your cardigan accurately

Pro tip: The Reddit user noted that YouTube resources were “pretty limited”, but there are excellent tutorials available if you know where to look.

4. How Do You Choose the Right Zipper for a Crochet Cardigan?

Not all zippers are created equal. For a cardigan, you need a separating zipper—one that opens completely at the bottom.

Zipper selection checklist:

• Separating zipper: Essential for cardigans and jackets

• Length: Measure the front opening of your cardigan and choose a zipper slightly longer (you can shorten it)

• Color: Match or complement your yarn

• Weight: Choose a zipper appropriate for the weight of your cardigan (lighter for fine yarn, heavier for bulky)

Shortening a zipper: If your zipper is too long, you can shorten it from the bottom. The Reddit user would benefit from learning this technique.

5. How Do You Prepare the Lining for a Crochet Cardigan?

The lining should be slightly smaller than the cardigan to prevent bunching.

Step-by-step lining preparation:

1. Lay your cardigan flat and measure the front panels, back, and sleeves

2. Cut your lining fabric using these measurements, adding a ½-inch seam allowance

3. Pin the lining pieces together (right sides facing) and sew the shoulder and side seams

4. Try the lining inside the cardigan to check the fit

5. Trim any excess fabric

Important: The gaps in crochet stitches can be a challenge when sewing a lining. To avoid visible stitching, use a matching thread and sew close to the edge of the crochet fabric.

6. How Do You Sew a Zipper into a Crochet Cardigan?

This is the step that intimidates many crocheters—but it's simpler than it seems.

Step-by-step zipper installation:

1. Open the zipper fully

2. Pin the zipper to one side of the cardigan opening, with the zipper teeth facing the inside

3. Mark the start and end points with pins or stitch markers

4. Sew the zipper in place using a zipper foot on your sewing machine, or hand-sew with a running stitch

5. Repeat on the other side, making sure both sides align evenly

6. Test the zipper to ensure smooth operation

Machine-sewing tip: Use a short, narrow zigzag stitch when sewing near the crochet edge to prevent the yarn from pulling.

7. Should You Sew the Lining and Zipper Together or Separately?

There are two approaches, and both work.

Option 1: Sew the zipper to the cardigan first, then attach the lining

• Sew the zipper directly to the crochet edges

• Then hand-stitch or machine-stitch the lining to the inside, covering the zipper tape

Option 2: Attach the lining and zipper as one unit

• Sew the zipper to the lining fabric first

• Then attach the assembled lining+zipper to the cardigan

• This method gives a cleaner finish and is often easier for beginners

The Reddit user's situation: Since they've never used a sewing machine, Option 1 (zipper to cardigan first, then hand-stitch lining) might feel less intimidating.

8. What Are the Most Common Mistakes When Adding a Zipper to Crochet?

Mistake 1: Using a non-separating zipper

• A cardigan needs to open fully at the front—use a separating zipper

Mistake 2: Not pinning before sewing

• Crochet stretches. Pinning prevents shifting and ensures straight alignment

Mistake 3: Sewing too close to the crochet edge

• Leave a small margin to prevent yarn from pulling or stretching

Mistake 4: Forgetting to backstitch

• Secure the beginning and end of your stitching to prevent unraveling

Mistake 5: Not testing the zipper before sewing

• Always test that the zipper opens and closes smoothly before committing to stitching

9. Why a Reliable Sewing Machine Makes All the Difference

The Reddit user is open to trying a sewing machine but feels “daunted”. The right machine can turn that fear into confidence.

What to look for in a sewing machine for crochet projects:

• Zipper foot capability: Essential for sewing zippers cleanly

• Adjustable stitch length and width: Zigzag stitches are recommended for crochet edges

• Consistent tension: Prevents puckering and uneven seams

• Durable construction: Handles multiple layers of fabric and yarn

10. The Bottom Line: You Can Do This

The Reddit user's hesitation is understandable—but the reward is worth the effort. A lined, zippered cardigan is not just a garment; it's a statement of craftsmanship.

Key takeaways:

• Start with the right materials: Separating zipper, quality lining fabric, matching thread

• Pin everything: Crochet stretches; pins prevent shifting

• Test before you commit: Check zipper function and fit before sewing

• Consider machine-sewing: It's faster, stronger, and gives a professional finish

• Don't be afraid to learn: Every expert was once a beginner
