Easy Crochet Throw – Alternating SC & HDC Stitch Blanket Pattern

This pattern alternates two of the most basic stitches in crochet: single crochet (sc) and half double crochet (hdc). By switching between sc and hdc across each row (or in some cases, every other row), you create a soft and stretchy fabric with subtle texture and visual interest.

This technique is easy enough for beginners to pick up but still offers a polished finish that can look more advanced. It's an ideal stitch pattern for making throws, baby blankets, scarves, and more. The best part is how versatile it is, you can keep the look minimal with one solid color or add playful stripes and blocks with different yarns.

Yes, it's excellent for beginners! Both single crochet and half double crochet are foundational stitches in crochet. This pattern gives you the chance to practice both while creating something beautiful and useful. The repeat is simple and easy to remember, making it perfect for relaxing crochet sessions, travel projects, or working in front of the TV. If you're just starting out, this project helps you learn how stitch height affects fabric texture and drape. It also forgives slight tension changes that are less noticeable than in more complex stitch patterns.

To crochet a blanket using alternating sc and hdc stitches, you start with a foundation chain in an even number. Then, work one sc in the first stitch, one hdc in the next, and continue alternating across the row. Each following row simply continues the same pattern: sc in the first stitch, hdc in the next, repeating to the end.

The consistency of alternating creates a rhythmic, meditative pattern that's easy to track and great for any size project. You’ll end up with a dense but stretchy fabric that lays flat and shows off color changes beautifully.

This stitch combination creates a texture that is both structured and flexible. The shorter single crochet stitches add tightness and stability, while the taller half double crochets give the blanket more flow and softness. The result is a slightly ridged surface with just the right amount of texture, not too bumpy and not too plain.

It also lays very flat, which is great for throws and baby blankets. When worked in colorful yarn or stripes, the texture catches the light beautifully and gives a tactile, cozy feel.

Yes, this stitch pattern is perfect for a baby blanket. It creates a soft, slightly stretchy fabric that is both warm and breathable. Use a baby-friendly yarn like soft acrylic, bamboo blends, or cotton for the best results. You can customize your blanket in soft pastels or bold brights depending on the theme. Plus, the simple texture is safe for babies, no large holes or raised stitches that little fingers can get stuck in. It's also machine washable when made with the right yarn, which makes it a favorite choice for parents.

To start, you’ll need an even number of stitches in your foundation chain. For a standard throw size (around 50" wide), this could be anywhere between 110–140 chains, depending on your yarn, hook size, and gauge. Always start by making a small swatch, 20 stitches wide by 10 rows high, to measure your stitch width. Then multiply that by the width you want. Since this stitch pattern doesn’t require a multiple beyond an even count, you have flexibility when adjusting for size.

One of the best features of this stitch combo is that it stays flat naturally. Unlike patterns that rely heavily on taller stitches or skipping chains, the sc/hdc pattern has a balanced structure that resists curling. This makes it perfect for blankets, especially when you want a clean edge without needing a heavy border. However, always make sure your tension is even and that you’re not pulling your chain row too tight. Adding a simple border in a single crochet helps maintain structure over time.

Worsted weight (category 4) yarn is ideal for this pattern, it gives the throw a good balance between warmth and drape. Choose a soft, washable yarn like Red Heart Soft, Caron Simply Soft, Paintbox Yarns, or Lion Brand Basic Stitch. Cotton-blend yarns also work beautifully for a slightly lighter, breathable throw. For added interest, try self-striping yarns or color-change cakes like Mandala or Ombre-style yarns to let the yarn do the colorwork for you.

Each row consists of a repeating sequence of sc and hdc stitches, so the texture looks uniform. To count rows accurately, look for the turning chains or use stitch markers every 10 rows. Another tip is to track rows in a notebook or tally app, especially if you're alternating colors. Since both stitches are similar in height, the rows blend smoothly but the edge of your blanket will have a neat, even line of stitches that can be easily counted when laid flat.

Time depends on the size of your blanket, your yarn weight, and your crochet speed. A standard throw (50" x 60") using worsted weight yarn may take 15–20 hours to complete for most crocheters. Because the stitch pattern is repetitive and easy, it’s perfect for working in short sessions over a week or two.

Using thicker yarn or a larger hook can cut the time significantly. It's also great as a stash buster since you can pick up where you left off without re-learning a complex pattern.
