The pattern is worked flat in one piece, making it portable and easy to manage, and the detailed instructions below will guide you through every step.

Materials Needed

Before you begin, gather the following materials to ensure a smooth knitting experience:

• Yarn: Worsted weight yarn in three colors:
  • Midnight Navy (MC): Approximately 1200 yards
  • Silver Sparkle (CC1): Approximately 300 yards
  • Soft White (CC2): Approximately 200 yards
• Needles: US 8 (5 mm) knitting needles
• Notions: Tapestry needle for weaving in ends
• Gauge: 18 stitches and 24 rows = 4 inches in stockinette stitch (always check your gauge for best results)

Pattern Overview & Abbreviations

Finished Size: Approximately 48 inches wide x 60 inches long.

Abbreviations:

• K = knit
• P = purl
• K2tog = knit two together (right-leaning decrease)
• SSK = slip slip knit (left-leaning decrease)
• YO = yarn over (increase creating an eyelet)
• MC = main color (Midnight Navy)
• CC1 = contrast color 1 (Silver Sparkle)
• CC2 = contrast color 2 (Soft White)

Pattern Notes: The blanket is worked flat in one piece. The lightning bolt motif is created using a combination of stockinette, reverse stockinette, and slipped stitches to form raised zigzag ridges. The silver sparkle yarn (CC1) is held double with MC for the bolt sections to add shimmer. The white bolt (CC2) is also held with MC for consistency and to blend the colors seamlessly.

Step-by-Step Instructions

Getting Started: Cast On & Bottom Border

With your MC yarn, cast on 216 stitches loosely. This will give you the 48-inch width based on the gauge.

Rows 1-8 (Garter Stitch Border): Knit every stitch across all 8 rows. This creates a sturdy, non-curling border for the bottom of your blanket.

Body of the Blanket: First Lightning Bolt Section (CC1 - Silver)

Now you will begin the main body, incorporating the first lightning bolt motif.

Row 9 (Right Side): K8 (border), *K20 with MC, switch to CC1+MC held together, K8, switch back to MC, K20*, repeat from * to * across the row, ending with K8 (border).

Row 10 (Wrong Side): K8, *P20 with MC, P8 with CC1+MC, P20 with MC*, repeat from * to *, end with K8.

Rows 11-20: Repeat Rows 9 and 10 for 10 more rows (for a total of 12 rows of the first bolt section). This establishes the vertical stripe of the bolt at 8 stitches wide.

Shaping the Zigzag: Decreases & Yarn Overs

Now we begin the zigzag shaping that creates the lightning bolt effect. This is done by decreasing on one side and increasing on the other, creating a diagonal slant.

Row 21 (Right Side): K8, *K20 MC, with CC1+MC: SSK, K4, K2tog, YO, K2, YO, SSK, K4, K2tog, K20 MC*, repeat from * to *, end with K8.

Row 22 (Wrong Side): K8, *P20 MC, with CC1+MC: P8, P2tog, P2, P2tog, P8, P20 MC*, repeat from * to *, end with K8.

Continuing the Zigzag: Continue working the zigzag decreases and yarn overs on every Right Side row, and the corresponding purl decreases on Wrong Side rows, until the CC1+MC section has decreased to 4 stitches wide. This will take approximately 12-14 rows total.

Widening the Bolt: Once the bolt is at its narrowest (4 stitches), begin increasing back out symmetrically over the next 12 rows to return to 8 stitches wide. To do this, work the increases (YO) on the opposite side of the decreases to reverse the slant. Essentially, you are mirroring the decrease rows.

Completing the First Bolt: After completing the first full lightning bolt (approximately 36 rows total from start to finish), you will have a complete silver zigzag.

Straight Section & Second Bolt (CC2 - White)

Straight MC Section: Work 12 rows straight with MC only across the entire row (no CC1+MC). This provides a visual break between the bolts.

Second Bolt (Opposite Direction): Now, create a second lightning bolt in the opposite direction using CC2 (Soft White) held with MC.

• Start with 8 stitches wide, just like the first bolt.
• Instead of decreasing to 4, you will increase to 12 stitches wide first.
• Work the zigzag in the opposite slant by using SSK on the left side and K2tog on the right side (the reverse of the first bolt). This will make the bolt slant in the opposite direction.
• After reaching 12 stitches wide, decrease back down to 8 stitches to complete the full bolt shape.

Repeating the Sequence

Repeat the following sequence until the blanket measures approximately 56 inches from the cast-on edge, ending with a CC1+MC bolt:

1. MC straight section (12 rows)
2. CC1+MC bolt (Silver)
3. MC straight section (12 rows)
4. CC2+MC bolt (White, opposite direction)

Finishing: Top Border & Bind Off

Top Border: Once your blanket reaches the desired length (approximately 56 inches), work 8 rows of garter stitch with MC for the top border, matching the bottom border.

Bind Off: Bind off all stitches loosely. A loose bind-off is crucial to prevent the edge from pulling in and ruining the drape of the blanket.

Weave in Ends: Using your tapestry needle, carefully weave in all loose ends on the wrong side of the blanket. Be sure to secure them well, especially where you changed colors.

Blocking: Gently block the blanket to shape and enhance stitch definition. Lay it flat on a blocking mat, pin to the correct dimensions (48" x 60"), and mist with water. Allow to dry completely before removing pins.

Your Stardust Lightning Bolt Throw Blanket is now complete! This celestial piece will be a stunning addition to your home, perfect for cozy evenings under the stars. Enjoy your handcrafted heirloom!
