Watermelon Ripple Crochet Baby Blanket Pattern

This free double crochet ripple baby blanket pattern combines colorful stripes with a border that straightens the wavy ends. Named Watermelon for its two shades of pink and soft green, this blanket can be made in any three colors you love.

The repeating stitch pattern is enjoyable to work once you establish the increases and decreases. Written instructions and crochet stitch diagrams help you follow the ripples, and the starting-chain multiple makes it easy to customize the blanket’s width and length.

Pair your finished blanket with a crochet baby hat for a thoughtful handmade gift.

About This Double Crochet Ripple Baby Blanket

This blanket is worked back and forth in rows of double crochet, with increases forming the peaks and decreases shaping the valleys. Change colors after each row, carrying the unused yarn along the sides to reduce the number of ends to weave in.

The finishing border uses stitches of different heights to fill the ripple edges, followed by two rounds of single crochet worked in the back loops. Keep the watermelon-inspired colors or make it your own with a different palette.
