    Video Tutorial

    In the video below, I walk you step-by-step through crocheting your square star blanket.

    Sizes / Measurements

    • Using two balls of Mandala Gradient creates a blanket that’s approximately 31” x 31” (pink version pictured).
    • Using two balls of Mandala Gradient, plus adding three rounds of a third yarn creates a blanket that measures 34” x 34” (green version pictured).
    • Follow instructions in the “Increasing the Blanket Size” section below to create a larger blanket.

    Gauge

    15 rounds of star measures approximately 27” across

    Gauge is checked after Round 2 of star section to avoid making a separate gauge swatch.

    Abbreviations + Glossary (US Terms)

    ch – chain

    chsp – chain space

    dc – double crochet

    dc2tog – double crochet two together

    dc3tog – double crochet three together

    hdc – half double crochet

    PM – place marker

    rep – repeat

    RS – right side

    sc – single crochet

    sk – skip

    slst – slip stitch

    st(s) – stitch(es)

    tr – treble (triple) crochet

    tr2tog – treble crochet two together

    tr3tog – treble crochet three together

    WS – wrong side

    Skill Level

    This is an intermediate level crochet pattern. It's quite straightforward if you follow along with the video tutorial, but it does require some counting, increasing and decreasing. (I promise, it's worth it though!)

    Overall Pattern Notes

    • If you’re new to reading crochet patterns, check out more info here.
    • The number in parenthesis at the end of each round is the number of stitches per star or blanket side.
    • Gauge is measured after Round 2 in the pattern.
    • Blanket is worked in turned rounds. 
    • A chain 2, 3, or 4 at the beginning of a round counts as a stitch throughout. 
    • A chain 2 also counts as the first half of a dc2tog or dc3tog decrease. This is noted in instructions when relevant.

    Center Star

    Working from the darkest end of Color A yarn:

    Preferred Foundation: Create a magic ring.Alternative Foundation: Ch 4, slst to first ch to create a loop.

    Foundation Round (WS): Ch 1, sc 8 in magic ring or loop, slst to first st to join; turn. (8)

    Round 1 (RS): Tightly ch 3, 2 dc in next sc, 2 dc in each remaining sc, dc in base of ch 3 from beginning of round, slst to first st to join; turn. (16)

    Round 2 (WS): Tightly ch 3, 2 dc in next st, 2 dc in each remaining st, dc in base of ch 3 from beginning of round, slst to first st to join; turn. (32)

    ! Gauge Check !

    Measure width and height of circle. It should measure 4” (10 cm) in each direction.

    • If your circle is measuring less than 4”, increase your hook size and remake first few rounds.

    Important Notes From This Point in the Star Forward:

    • It can be easy to accidentally add an extra stitch at the end of the round. The stitch the beginning chain 2 is worked into can look like the last stitch of the round, but it was actually the first stitch of the round. Do not mistake this for a fresh stitch to work into because it will add an extra stitch to each round.
    • To join each round, make sure to slip stitch into the top of the decrease from the beginning of the round. (Do not accidentally slip stitch into the turning chain as done above.)
    • There’s now an extra slip stitch at the end of each round in order to position the yarn for the upcoming round. 

    Round 3 (RS): Ch 2, dc in next dc (dc2tog made), 2 dc in next dc, ch 2, 2 dc in next dc, *dc2tog, 2 dc in next dc, ch 2, 2 dc in next dc; rep from * to end of round, slst to top of first dc2tog, slst into next dc; turn. (5 dc per side, 8 ch2sp corners created)

    Round 4 (WS): Ch 2, dc2tog (dc3tog made), dc, (2 dc, ch 2, 2 dc) in corner ch2sp, *dc, dc3tog, dc, (2 dc, ch 2, 2 dc) in corner ch2sp; rep from * until 1 dc remains, dc in last dc, slst to top of first dc3tog, slst into next dc; turn. (7 dc/side)

    Round 5 (RS): Ch 2, dc2tog (dc3tog made), dc in each dc to corner, (2 dc, ch 2, 2 dc) in corner space, *dc in each dc until 1 st before dec, dc3tog, dc in each dc to corner, (2 dc, ch 2, 2 dc) in corner space; rep from * through last corner, dc in each remaining dc, slst to top of first dc3tog, slst into next dc; turn. (9 dc/side)

    The first several rounds of a crochet ripple star.

    Rep Round 5 ten more times to create a total of 15 dc rounds. Each round should increase by 2 dc per side and 16 dc total per round. In the 15th round, you should have 29 dc/side. 

    You may run out of Color A yarn toward the end of your star. If so, join the lightest end of Color B yarn and continue.

    Squaring the Star

    If you have not yet transitioned to using Color B yarn, do so wherever Color A is finished.

    Place Markers:

    The round you just finished was a RS round. With this round facing up:

    Right Handed: Counting clockwise around star from the live loop, PM in 1st, 3rd, 5th and 7th corners.

    Left Handed: Counting counter-clockwise around star from the live loop, PM in 1st, 3rd, 5th and 7th corners.

    These four markers now indicate the blanket corners. In the following rounds, we’ll work to create a four-sided square. To do this, the four unmarked star corners will begin to be treated as regular stitches in order to be “absorbed” into the square.

    Move markers up as each round is worked until the four blanket corners are well defined and there’s no risk of confusion.

    Round 16 (WS):
    First blanket side (to begin): …Ch 3, tr2tog (counts as a tr3tog), 1 tr, 4 dc, 4 hdc, 4 sc, (sc, ch 3, sc) in marked corner space…

    First blanket side (to complete):...6 sc, 4 hdc, 4 dc, slst to top of ch 3; turn. (61 sts/blanket side)

    Round 18 (WS):
    First blanket side (to begin): …Ch 3 (counts as first dc), 3 dc, 12 tr, (2 tr, ch 2, 2 tr) in marked corner space…

    Second, third, and fourth blanket sides:...12 tr, 9 dc, 5 hdc, 9 sc, 5 hdc, 9 dc, 12 tr, (2 tr, ch 2, 2 tr) in marked corner space…

    First blanket side (to complete): ....9 tr, 12 dc, slst to top of ch 2; turn. (77 sts/blanket side)

    Increasing Blanket Size (Optional)

    The size of your blanket can now be easily increased by working additional rounds in double crochet as described in Round 22. You may either use a solid color category #4 yarn that’s similar in thickness to Mandala Gradient, or attach a new color of Mandala Gradient.

    In the green sample blanket pictured, Lion Brand Basic Stitch was used to add three additional rounds.

    With Color C:

    Round 22 (WS): Ch 3 (counts as first dc), *dc to corner, (2 dc, ch 2, 2 dc) in corner; rep from * 3 more times, dc to end of round; slst to top of ch 3; turn. (81 sts/blanket side)

    Repeat Round 22 until desired blanket size is reached.

    Finishing

    Blocking: Blocking is important to smooth out any waviness that remains from squaring off the star. Pin blanket edges first, using T-pins liberally to ensure the edges are straight. Next pin the star points so the star can “open up” as much as possible. This step is essential if your blanket has some waviness to smooth out. See video tutorial for demonstration.

    Thoroughly steam blanket using a steamer or iron with steam setting, but do not touch heated surface directly to yarn.

    Weave in remaining ends: Learn more about finishing your crochet projects.
