Pattern Details

Skill Level

Intermediate — perfect for crocheters with some experience. The pattern uses more intricate stitches (bobbles), shaping (working from the centre out), and clean finishing techniques.

Finished Size

The pattern is written for a 34″ x 45″ crib blanket but is easily resizable. Each additional band of colour added to the rainbow adds approximately 7″ to the width and 3.5″ to the length — so you can scale up to a toddler, throw, or full-sized blanket.

Gauge

4″ x 4″ (10cm x 10cm) = 13 sc x 14 rows with 5 mm (US H-8) crochet hook

The Bobble Stitch That Makes This Blanket Special

The texture in this rainbow crochet crib blanket comes from the classic bobble stitch — a beautiful raised cluster that creates the dimensional, tactile surface babies love.

How to work a bobble stitch: Yarn over, insert hook into stitch, yarn over and pull through (three loops on hook), yarn over and pull through two loops. Repeat that step four more times into the SAME stitch so you have five not-quite-complete dc stitches with six loops on the hook. Then yarn over and pull through all six loops. The bobble is now closed and sits proudly raised from the fabric.

The pattern alternates between increase rows (right side) and bobble rows (wrong side), with bobbles offset every other row to create the evenly distributed bobble profile you see in the photos.

Tips for Clean Colour Changes

The 5 colour bands in the rainbow crochet crib blanket need clean transitions to look polished. Here’s the technique:

1. Finish the last stitch with the old colour: Work until there are two loops on your hook with the old colour.
2. Yarn over with the new colour: Before completing the last stitch with the old colour, yarn over with the new colour.
3. Pull through loops: Finish the last stitch by pulling through the last two loops with the new colour.
4. Secure the old colour: Once you’ve changed colours, secure the yarn of the old colour by either crocheting over the tail or by weaving it in later.

This technique gives you crisp, clean colour transitions instead of muddy mixed-colour stitches at the boundary. Worth the extra few seconds per change.

Frequently Asked Questions

How long does the rainbow crochet crib blanket take to make? Most intermediate crocheters finish in 25-40 hours depending on speed. A great long weekend or week-of-evenings project.

Can I make this in different colours? Absolutely — that’s part of the fun. Try pastel rainbow, neutrals, jewel tones, monochrome ombre, or the recipient’s favourite colours. Just use the same yarn weight (#4) so your gauge holds.

How do I make the blanket bigger or smaller? Each additional band of colour adds about 7″ to the width and 3.5″ to the length. To make it smaller, use fewer colours. To make it bigger, add more bands. The Etsy PDF includes a sizing chart.

Is the bobble stitch hard? If you can double crochet, you can bobble. It just means working multiple incomplete dc stitches into the same stitch and pulling them all closed at once. The PDF walks through it with detailed instructions.

Can I machine wash this blanket? Yes. The recommended Lily Sugar ‘n Cream is a 100% cotton yarn — machine wash cold and tumble dry low. Always check your specific yarn label first.

Is the pattern available for free? The free version has been retired, but you can purchase the printable PDF on Etsy for a small fee. Your purchase supports the work that goes into designing, testing, and sharing patterns. Thank you!
