Pattern Details

Materials You’ll Need

To make this block stitch blanket as shown, gather the following materials. The soft baby-weight yarn keeps the finished piece light and drapey, but you can absolutely substitute any DK or light worsted yarn that gives you the right gauge.

• Yarn (Color A — main): 2 balls of Bernat Softee Baby in a soft neutral (shown in Flannel)
• Yarn (Color B — contrast): 1 ball of Bernat Softee Baby in a coordinating shade (shown in Blue Jeans)
• Crochet hook: 4mm (US G/6) crochet hook — I love this ergonomic set
• Tapestry needle for weaving in ends
• Scissors: a sharp pair of yarn scissors

Pattern Notes

Before you dive into the block stitch blanket, a few quick notes:

• This pattern is written in US crochet terms.
• The stitch works in multiples of 3 + 1 — so to resize, choose any chain count that fits the formula (e.g. 70, 100, 130, 160).
• The starting chain shown (106) gives roughly 30″ wide at the listed gauge. Adjust up or down based on your desired finished width.
• Color changes happen at the end of every row — leave 4–5″ tails for weaving in and try to change colors on the same edge each time for a cleaner finish.
• Make a small gauge swatch first if you want your finished blanket to land at exact measurements.

Abbreviations

• beg = beginning
• ch = chain
• sc = single crochet
• dc = double crochet
• sk = skip
• sp = space
• slst = slip stitch
• st(s) = stitch(es)
• rep = repeat

Main Section

With Color B, chain 106 to start (or any multiple of 3 + 1).

Row 1: Sc in 2nd ch from hook, *sc, ch 2, sk 2 ch* repeat to last 2 stitches, 2 sc, turn.

Row 2: Change to Color A, ch 3, *3 dc in ch-2 sp from previous row* repeat to last 2 sc, dc in last sc, turn.

Row 3: Change to Color B, sc, *sc, ch 2, sk 2 ch* repeat to last 2 stitches, 2 sc, turn.

Repeat Rows 2 and 3 until your block stitch blanket reaches approximately 31″ or your desired length. Fasten off and weave in ends.

Border

The border is worked with two rounds of double crochet, with 3 dc in every corner to prevent pulling. You can start in any corner. For the top and bottom edges, dc in every stitch. For the side edges, evenly space your double crochets — they work out to roughly 2 dc for every row of the main body.

Round 1: Beginning in any corner, slst with Color B and ch 3, 2 dc in base of same st, then *dc in every st around to next corner, 3 dc in corner* repeat until you return to the beginning ch 3. Join with slst to top of ch 3.

Round 2: Ch 3, 2 dc in base of same st, then *dc in every st around to next corner, 3 dc in corner* repeat until you return to the beginning ch 3. Join with slst to top of ch 3. Fasten off and weave in ends.

Tips for the Best Block Stitch Blanket

• Pick high-contrast colors. The textured block effect really pops when there’s a clear difference between your two colors — think cream + navy, oatmeal + rust, or soft pink + charcoal.
• Weave in ends as you go. Since this pattern changes colors every row, you’ll have a lot of tails. Stop every 10–12 rows to weave them in and save yourself a marathon finishing session.
• Don’t pull your turning chain too tight. The ch 3 at the start of each Row 2 counts as your first dc, so keep it relaxed for a clean edge.
• Block when finished. A gentle wet block evens out the texture and makes the blanket drape beautifully.
• Customize the size easily. The 3+1 multiple means you can make this anywhere from a stroller blanket to a king-size throw — just adjust your starting chain.
• Use a stitch marker in the first stitch of each row to make finding it easier when changing colors.

Frequently Asked Questions

What is the block stitch in crochet?

The block stitch is a textured crochet technique that alternates rows of single crochet with “blocks” of three double crochets worked into chain spaces from the row below. The result is a soft, dense fabric with a beautiful basket-weave-like texture — perfect for a block stitch blanket, scarf, or pillow cover.

Can I make this block stitch blanket bigger?

Absolutely. The block stitch is worked in multiples of 3 + 1, so you can resize this block stitch blanket to any dimension by adjusting your starting chain. For a throw, try a chain of 160. For a king-size blanket, go up to 250 or more. Just remember you’ll need more yarn — roughly double for each size up.

What yarn weight works best for this pattern?

This block stitch blanket was designed for DK or light worsted yarn (weight #3) with a 4mm hook, which gives a soft drape ideal for a lap or baby blanket. You can absolutely use worsted (#4) with a larger hook for a quicker, chunkier finish, or even a sport weight for a more delicate result.

Is this pattern good for beginners?

Yes — this is one of the best beginner crochet blanket patterns out there. If you know how to chain, single crochet, and double crochet, you have everything you need. The two-color rotation builds confidence with color changes without being overwhelming.

How much yarn do I need for a block stitch blanket?

For a 30″ × 35″ lap-sized block stitch blanket in DK yarn, plan for approximately 2 balls of your main color and 1 ball of your contrast color (about 1,200 total yards). For a larger throw, double or triple those amounts depending on your finished dimensions.

Yes — you’re welcome to sell finished items you make from this block stitch blanket pattern. A credit linking back to SeeLoveShare.it is always appreciated, but never required. The pattern itself remains the property of SeeLoveShare LLC and may not be reproduced or redistributed.
