The Gentle Waves Baby Blanket uses a version of the Ripple Stitch. The gentle waves are made by using single and double crochet in each row.

The Gentle Waves Baby Blanket can be made in 4 sizes:
Preemie
Cradle
Receiving
Stroller

The crochet pattern can be adjusted to any size you prefer by using the Gauge:
16 dc x 8 rows = 4”
The stitch count is a multiple of 9

I made the Preemie size and used:
Bernat Softee Baby Yarn (362 yds/331 m) (5 oz/140 g)
1450 - 2200 yds #3 Ply Lightweight or DK Weight Yarn
US G Crochet Hook or 4 mm Crochet Hook

So surround your little one in the soothing comfort of these gentle waves. The gentle waves crochet pattern has 4 sizes to surround your baby in.
