Materials Needed

Before you begin your journey to crochet this night sky masterpiece, gather the following materials. Having everything ready will make your crafting session smooth and enjoyable.

• Yarn: Worsted weight yarn in 5 colors. The approximate yardage is 1800 yards total. Here is the color breakdown:
  • Color A: Deep Navy (approx. 400 yards)
  • Color B: Midnight Purple (approx. 350 yards)
  • Color C: Teal (approx. 350 yards)
  • Color D: Emerald Green (approx. 350 yards)
  • Color E: Soft White (approx. 350 yards)
• Crochet Hook: 5.5 mm (I-9) crochet hook. This size is ideal for worsted weight yarn to create a dense, warm fabric.
• Other Tools: Yarn needle for weaving in ends, scissors, and stitch markers (optional, but helpful for keeping track of rows).

Gauge Information

Gauge: 4 star stitches x 3 rows = 4 inches (10 cm) in pattern. It is crucial to check your gauge before starting. If your gauge is too loose, your blanket will be larger and use more yarn. If it's too tight, it will be smaller and stiffer. Adjust your hook size if needed to achieve the correct gauge.

Step-by-Step Instructions

This blanket is worked in rows using the star stitch, which creates a beautiful, textured star-like pattern. The color changes mimic the flowing bands of the aurora. Follow these detailed instructions carefully, and you'll be amazed at the beautiful fabric you create. The pattern is broken down into manageable steps, including a foundation row, setup row, and the repeating star stitch rows.

Foundation Row

With Color A (Deep Navy), chain a multiple of 3 + 2. For a throw size (approximately 50" x 60"), chain 152. This foundation chain will determine the width of your blanket. Ensure your chain is not twisted before you begin the next row.

Row 1 (Setup Row)

This row creates the base structure for the star stitches. It is a simple combination of single crochets and chain spaces.

1. Single crochet (sc) in the 2nd chain from your hook.
2. *Chain 1 (ch 1), skip 1 chain, sc in the next chain.*
3. Repeat from * across the entire row. You will end with a sc in the last chain. Turn your work.

You will now have a series of sc stitches with ch-1 spaces between them. This is the foundation for your star stitches.

Row 2 (Star Stitch Row)

This is where the magic happens! The star stitch is created by pulling up loops from multiple points and joining them together. Follow these steps carefully for your first star.

1. Start the row: Chain 2 (counts as your first double crochet).
2. Create the first half-star: Insert your hook into the first ch-1 space, yarn over, and pull up a loop. You should have 2 loops on your hook. Insert your hook into the next sc, yarn over, and pull up a loop. You should now have 3 loops on your hook. Yarn over and pull through all 3 loops on your hook. This is a half-star.
3. Close the star: Chain 1 to close the star. This ch-1 space is where you will work your next row's sc.
4. Create the full stars: *Insert your hook into the same sc you just used (the one from the half-star), yarn over, and pull up a loop. You should have 2 loops on your hook. Insert your hook into the next ch-1 space, yarn over, and pull up a loop. You should have 3 loops on your hook. Insert your hook into the next sc, yarn over, and pull up a loop. You should now have 4 loops on your hook. Yarn over and pull through all 4 loops on your hook. Chain 1 to close the star.*
5. Repeat: Repeat from * across the row until you have made a star in every ch-1 space.
6. Finish the row: End with a double crochet (dc) in the last sc of the row. Turn your work.

Pro Tip: Keep your tension consistent. If you pull the loops too tight, the stars will be difficult to work into on the next row. If they are too loose, the fabric will look sloppy.

Row 3 (Return Row)

This row creates the "valleys" between the stars and sets up the next row of star stitches.

1. Chain 1, and single crochet in the first double crochet of the previous row.
2. *Chain 1, single crochet in the ch-1 space of the next star.*
3. Repeat from * across the row. You will be working a sc into each of the ch-1 spaces that closed the stars in the previous row.
4. Finish the row with a single crochet in the top of the turning chain (the ch-2 from the previous row). Turn your work.

Row 4 (Star Stitch Row)

This row is a repeat of Row 2, but now you will be working your stars into the ch-1 spaces between the sc of the previous row (Row 3).

1. Chain 2 (counts as first dc).
2. Insert hook into the first ch-1 space, yarn over, pull up a loop. Insert hook into the next sc, yarn over, pull up a loop (3 loops on hook). Yarn over, pull through all 3 loops. Chain 1.
3. *Insert hook into the same sc you just used, yarn over, pull up a loop. Insert hook into the next ch-1 space, yarn over, pull up a loop. Insert hook into the next sc, yarn over, pull up a loop (4 loops on hook). Yarn over, pull through all 4 loops. Chain 1.*
4. Repeat from * across. End with a dc in the last sc. Turn.

You will now alternate between Row 3 (return row) and Row 4 (star stitch row) for the remainder of the blanket, following the color sequence below.

Color Sequence

To create the beautiful aurora effect, follow this color sequence. Each color is worked for 4 rows (one star stitch row, one return row, one star stitch row, one return row).

• Rows 1-4: Color A (Deep Navy)
• Rows 5-8: Color B (Midnight Purple)
• Rows 9-12: Color C (Teal)
• Rows 13-16: Color D (Emerald Green)
• Rows 17-20: Color E (Soft White)
• Rows 21-24: Color D (Emerald Green)
• Rows 25-28: Color C (Teal)
• Rows 29-32: Color B (Midnight Purple)
• Rows 33-36: Color A (Deep Navy)

Repeat this color sequence until the blanket reaches your desired length, ending with a full sequence of 36 rows. This will create a symmetrical gradient effect, with the deep navy at both edges and the soft white in the center.

Border

The border adds a polished, finished look to your blanket and helps to stabilize the edges.

1. Round 1: With Color E (Soft White), work a round of single crochet evenly around the entire blanket. Work 3 single crochet in each corner to ensure the corners lay flat and turn nicely.
2. Round 2: Work a round of reverse single crochet (also known as crab stitch). This is worked from left to right (or right to left if you are left-handed). Insert your hook into the next stitch to the right, yarn over, pull up a loop, yarn over, and pull through both loops on the hook. This creates a beautiful, twisted, rope-like edging.
3. Finish: Fasten off and weave in all ends with your yarn needle. Be sure to weave in ends securely so they don't come loose with use and washing.

Congratulations! You have just created a stunning Aurora Borealis Star Stitch Blanket.
