This crochet knit stitch tutorial walks you through the waistcoat stitch — also called the knit stitch in crochet — a clever single crochet variation that mimics the look of stockinette knitting. The waistcoat stitch is a single crochet worked between the left and right post of the stitch below, creating a smooth, uniform “V” pattern that gives crochet projects a polished, knitted appearance. It’s especially useful for colorwork patterns, lettering, and anywhere you want crisp vertical stitch alignment.

Once you’ve learned this stitch, you’ll start seeing places to use it everywhere — beanies, sweaters, baby items, anything where you want the look of knit but the speed and structure of crochet. It takes a bit of practice to get your tension right (the stitch can feel tight at first), but the polished finished look is worth the learning curve.

Why You’ll Love the Crochet Knit Stitch (Waistcoat Stitch)

• Looks like knitting — creates a smooth, uniform “V” stitch pattern that mimics stockinette
• Perfect stitch alignment — stitches stack vertically, making it ideal for colorwork and lettering
• Single crochet base — if you can single crochet, you can learn this stitch
• Polished finish — gives any crochet project a more elevated, professional look
• Versatile — works in flat panels, in the round, and in colorwork
• Great for hats and bags — the structured fabric holds shape beautifully

What Is the Waistcoat Stitch?

The waistcoat stitch (also called the crochet knit stitch or split single crochet) is a variation of single crochet where you insert your hook between the two vertical posts of the stitch below — the “V” — instead of under the top loops. The result is a stitch that looks remarkably like a knit “V” stitch, with clean vertical alignment that’s perfect for tapestry crochet, colorwork, and lettering projects.

It’s typically worked in the round with the right side facing at all times, though you can also work it in flat rows with some practice. The stitch creates a denser, more structured fabric than traditional single crochet, which makes it especially good for items that need to hold their shape — bags, baskets, hats, and home decor pieces.

How to Crochet the Knit Stitch (Waistcoat Stitch)

Step 1: Foundation

Start with a row of regular single crochet stitches. This forms the foundation row that you’ll work the waistcoat stitch into. The waistcoat stitch is typically worked in the round (joined or unjoined), with the right side facing at all times.

Step 2: Identify the Posts

Look at the next stitch in your foundation row. You’ll see two vertical “legs” or posts forming a V shape on the front of the stitch. Instead of inserting your hook under the top loops (the way you would for a standard single crochet), you’ll insert it directly into the center of that V — between the two posts.

Step 3: Work the Stitch

• Insert your hook between the two posts of the stitch below (into the center of the V)
• Yarn over and pull up a loop (you’ll have 2 loops on your hook)
• Yarn over and pull through both loops
• You’ve completed one waistcoat stitch

Step 4: Continue

Continue inserting your hook between the posts of each stitch around. Keep your tension consistent — the waistcoat stitch can feel tight at first because you’re working into a smaller space than a standard single crochet. Going up a hook size or two from what you’d normally use can help.

Tips for Success

• Use a larger hook — go up one or two sizes from what you’d normally use for single crochet to compensate for the tighter stitch placement
• Keep tension loose — if you’re a tight crocheter, focus on relaxing your grip while learning this stitch
• Work in the round — the waistcoat stitch is much easier in the round than in flat rows because you’re always working on the right side
• Practice with light-colored yarn — it’s easier to see the V shape clearly when you’re learning
• Take your time on the first row — the second and subsequent rows are much easier once your foundation row is established
• Don’t worry about speed — the waistcoat stitch is slower than regular single crochet at first, but you’ll speed up with practice

Best Projects for the Waistcoat Stitch

Once you’ve got the technique down, here are the kinds of projects where the waistcoat stitch really shines:

• Tapestry crochet colorwork — the perfect vertical stitch alignment makes color changes crisp and clean
• Crochet beanies and hats — the structured fabric holds shape beautifully
• Project bags and totes — denser fabric means sturdier finished bags
• Lettering and graphic patterns — readable text needs precise stitch alignment
• Sweaters and tops — for that “did you knit or crochet this?” finish
• Baby items — the smooth, knit-like texture is soft against baby skin

Common Mistakes to Avoid

• Inserting under the top loops — that’s a regular single crochet, not the waistcoat stitch. Always insert between the posts (into the V).
• Pulling stitches too tight — keeps the V from forming clearly. Loose tension is your friend here.
• Working flat rows on your first try — start in the round to keep the right side always facing you.
• Skipping the foundation row — the waistcoat stitch needs a single crochet foundation to work into.
• Using the same hook size as standard single crochet — this stitch needs more room to breathe.
