- Worsted weight yarn in 7 rainbow colors: red, orange, yellow, green, blue, indigo, and violet (80-100 yards each)

Choosing Your Rainbow Color Palette
The beauty of a crochet baby rainbow blanket lies entirely in thoughtful color selection. For a classic bold look, use true primary and secondary colors with high saturation. For a pastel rainbow that suits soft nursery aesthetics, choose softer versions: blush pink, peach, butter yellow, mint green, sky blue, lavender, and lilac. A trendy muted rainbow works beautifully with dusty rose, terracotta, mustard, sage, slate blue, plum, and mauve. Choose whichever palette best complements the nursery decor.
Step-by-Step Pattern Instructions
Foundation Rows
With white yarn, chain 102 for a blanket approximately 30 inches wide. Row 1: Dc in 4th ch from hook and in each ch across. (100 dc) Rows 2-3: Continue in dc with white yarn. These three white rows create a clean, bright base for the first rainbow color stripe.
Rainbow Stripe Sequence
Switch to red yarn. Rows 4-9: Work 6 rows of dc in red. Rows 10-11: Switch to white, work 2 rows of dc as a divider. Rows 12-17: Switch to orange, work 6 rows of dc. Continue this pattern of 6 color rows followed by 2 white divider rows through all seven rainbow colors in order: red, orange, yellow, green, blue, indigo, and violet.
The white divider rows between colors are the secret to making each rainbow color pop with maximum visual impact. Without them, adjacent colors can blur together visually, especially in photographs. For clean color transitions, work the last yarn over of the final stitch in each section with the new color yarn. This places the color change precisely at the beginning of the new row for a crisp line. You can carry the white yarn along the side edge rather than cutting it each time to significantly reduce the number of ends to weave in later.

Repeat or Mirror the Rainbow
For a longer blanket, you have two excellent options. Option A: Repeat the entire rainbow sequence for a second full pass from red through violet again, creating a double rainbow effect. Option B: Mirror the rainbow by working backward from violet through red, creating a beautiful symmetrical pattern with the spectrum flowing in both directions. The mirrored version typically measures about 36 by 42 inches, which is the ideal size for a crib blanket.
Border
Round 1: Using white yarn, sc evenly around the entire blanket perimeter, working 3 sc in each corner stitch. Join with sl st. Round 2: Sc in each st around with 3 sc in each corner. Round 3: Work a playful picot border to complement the cheerful design: *sc in next 3 sts, ch 3, sl st in first ch to form picot* repeat around the entire edge. According to AllFreeCrochet’s baby blanket collection, borders that contrast with the main blanket pattern create the most visually appealing finished pieces.
Rainbow blankets pair beautifully with other colorful nursery items. Consider creating coordinating pieces like crochet baby milestone blanket to build a complete, cheerful nursery collection.
Managing Multiple Yarn Colors
Working with seven different colors plus white means managing a lot of yarn simultaneously. Wind each color onto a small cardboard bobbin or clip partial skeins with clothespins to prevent tangling. Work your yarn ends in as you go rather than saving them all for the end, because with this many color changes you could easily accumulate 30 or more loose ends to weave in if you wait until the blanket is complete.
Frequently Asked Questions
How do I prevent gaps at color changes?
Always change colors on the last pull-through of the previous row’s final stitch. Pull the new color yarn snug but not tight to close any visible gap at the transition. When weaving in the tail later, use it to close any remaining gap by sewing across the color join from the wrong side.
What if I cannot find all seven rainbow colors in the same yarn brand?
Mixing yarn brands is perfectly acceptable as long as the yarn weight and fiber content are the same across all colors. Check that the gauge is consistent by swatching each color before starting. Even slight variations in yarn thickness will show as noticeably uneven stripe widths in the finished blanket.
Can I make a rainbow blanket with granny squares instead of stripes?
Absolutely. Make 7 rows of granny squares, each row in a different rainbow color, and join them together with white yarn for a unified look. This modular approach allows you to work on individual squares during short crafting sessions and assemble the blanket later when all squares are complete.
