Step-by-Step Instructions

Pattern Notes

• The blanket is worked in rows from bottom to top.
• The pattern stitch creates a dense, textured fabric with a beautiful drape.
• Each color is used for 2 rows (a right-side row and a wrong-side row) to create a distinct stripe.
• The color sequence is A, B, C, D, E, F, G, then repeat from A.
• Chain stitches at the beginning of rows do not count as a stitch unless specified.

Foundation Chain

With Color A (Cherry Red), chain 121 (or any multiple of 6 + 1 for desired width). This gives you a blanket approximately 36 inches wide. For a wider throw, chain in multiples of 6 + 1 (e.g., 127, 133, etc.).

Row 1 (Right Side)

Single crochet (sc) in the 2nd chain from the hook. *Chain 3, skip 2 chains, sc in the next chain, chain 1, skip 2 chains, sc in the next chain; repeat from * across the row, ending with a sc in the last chain. Turn your work. You will have a series of ch-3 loops and ch-1 spaces across the row.

Row 2 (Wrong Side)

Chain 1 (does not count as a stitch), sc in the first sc. *Chain 3, sc in the next ch-3 loop (the large loop from the previous row), chain 1, sc in the next sc (the single sc between the ch-1 space); repeat from * across the row, ending with a sc in the last sc. Turn.

Row 3 (Right Side) – Color Change to B

Change to Color B (Pumpkin). Chain 1, sc in the first sc. *Chain 3, sc in the next ch-3 loop, chain 1, sc in the next sc; repeat from * across the row, ending with a sc in the last sc. Turn.

Row 4 (Wrong Side) – Color B

With Color B, repeat Row 2: Chain 1, sc in first sc, *chain 3, sc in next ch-3 loop, chain 1, sc in next sc; repeat from * across, ending with sc in last sc. Turn.

Continue the Pattern

Repeat Rows 3 and 4, changing colors every 2 rows in the following sequence: C (Bright Yellow), D (Spring Green), E (Turqua), F (Royal Blue), G (Amethyst), then back to A (Cherry Red). Continue this color sequence until the blanket measures approximately 60 inches long, ending after a wrong-side row (Row 2 or Row 4 of any color). Fasten off the final color and weave in all ends securely with a yarn needle.

Border

With Color A (Cherry Red), attach yarn to any edge of the blanket. Work a round of single crochet (sc) evenly around the entire blanket, working 3 sc in each corner to turn the corner smoothly. Join the round with a slip stitch (sl st) to the first sc. Fasten off and weave in the end.

Finishing

Weave in all remaining ends with a yarn needle. Block the blanket gently if desired to even out the stitches and enhance the drape. Your Chromatic Cascade Throw is now ready to brighten your home!
