When starting a knitting project, the first step is always the cast on—the technique used to place the first row of stitches onto your needle. While it may seem like a simple task, the type of knitting cast on you choose can significantly affect your project’s stretch, appearance, and structure.
This article explores the most common types of knitting cast ons, what they’re best used for, and how to decide which one is right for your project.
What Is a Cast On in Knitting?
A cast on is the foundation of your knitting. It sets up the stitches on your needle that you’ll work into as you knit the fabric. Different cast on methods offer varying levels of stretch, neatness, and stability—making the choice of cast on just as important as your yarn or needle.
Why Use Different Cast On Methods?
Not all cast ons are equal. Here’s why you might want to choose a specific technique:
- Stretchiness: Some cast ons are tight and firm; others are stretchy and flexible.
- Appearance: A decorative edge might be needed for projects like scarves or lacework.
- Speed and ease: Some cast ons are quick and simple for beginners, others are more advanced.
- Durability: Projects like socks or sweaters need a cast on that won’t unravel or wear out.
Most Popular Types of Knitting Cast Ons
1. Long-Tail Cast On
Best for: Most projects, especially garments and accessories
Features: Stretchy, clean edge, moderately easy to learn
This is one of the most widely used cast ons in knitting. You create a loop with a long tail of yarn, which also forms your first row. It gives a neat, stretchy edge.
Tip: Estimate your yarn tail by allowing about 1 inch per stitch, plus extra.
2. Knit Cast On
Best for: Beginners, adding stitches in the middle of a row
Features: Looser and less stretchy than long-tail, easy to control
This method involves creating stitches by knitting into each loop. It’s great for learning the knit stitch as you go.
3. Cable Cast On
Best for: Firm edges, button bands, collars
Features: Strong and decorative, less stretchy than long-tail
This is a variation of the knit cast on but uses the space between stitches to insert the needle, forming a more structured edge.
4. Twisted German Cast On (Old Norwegian)
Best for: Socks, hats, ribbed cuffs
Features: Extra stretch, durable, good for cold-weather wear
Similar to long-tail but with an extra twist. It’s a bit more complex but provides an elastic edge, perfect for garments that need give.
5. Provisional Cast On
Best for: Projects worked in both directions, seamless joins
Features: Temporary edge that can be unraveled to reveal live stitches
Usually done using a crochet chain or waste yarn. You remove it later to knit in the opposite direction or graft seamlessly.
6. Tubular Cast On
Best for: Ribbing in hats, socks, and cuffs
Features: Very stretchy, seamless and professional look
Used for 1×1 or 2×2 ribbing, this cast on creates a rolled edge that looks like it’s part of the rib pattern. It can be tricky but gives a polished result.
7. Picot Cast On
Best for: Decorative edges on lace, shawls, or baby garments
Features: Scalloped edge, less structure, slow to work
This adds a small decorative bump to each stitch and is more about form than function.
How to Choose the Right Cast On
| Project Type | Recommended Cast On | Why |
|---|---|---|
| Basic scarf | Long-tail cast on | Balance of stretch and neatness |
| Baby booties | Twisted German cast on | Soft, elastic edge |
| Sweater necklines | Tubular cast on | Seamless look and stretch |
| Lace shawl | Picot or provisional | Decorative or allows two-way knitting |
| Hat in the round | Long-tail or twisted German | Elastic, forms nice join |
| Button band or collar | Cable cast on | Firm and strong edge |
Tips for a Better Cast On
- Use stitch markers if casting on a large number of stitches.
- Avoid twisting your stitches if knitting in the round.
- Practice tension—not too tight or loose.
- Learn multiple methods to be ready for different patterns.
- Keep the tail long enough for long-tail variations.
