I made this blanket for my baby girl while I was expecting her. It took me a couple weeks as I went slow, but I thoroughly enjoyed it. There is an amazing video on YouTube by crochetblossom that does a swatch of this stitch. Super easy to follow.

I used Caron simply soft for this blanket as I wanted it to be really soft for my baby. Also the ripple stitch is denser than most other stitches and so the blanket has almost no holes...

Materials:

Yarn: Caron Simply Soft in Strawberry, Robin's egg and off white. 

Hook: 5.00

I used 2 skeins of each and was left with very little of each color. Ideally you could use 1 more skein of the first color and do the border in that color. 

Abbreviations:

C1: Color1 - Strawberry

C2: Color2 - Robin's egg

C3: Color3 - Off white

Note: ch3 does not count as a stitch.

With C1 ch mumtiples of 12 and then chain 3 more. I did a ch of 123.

Row1: dc in the 4th chain from hook, dc in the next 3 ch, *dc2t next 2 ch, dc2t next 2 ch, dc in next 3 ch, 2dc in each of next 2 ch, dc in next 3 ch*  repeat from * to * until you are left with 4 stitches. Then dc in next 3 stitches, work 2 dc in the last ch. (120) 

Row2: ch3 turn, dc in the same stitch as ch3, dc in the next 3 stitches, *dc2t next 2 stitches, dc2t next 2 stitches, dc in next 3 stitches, 2dc in each of next 2 stitches, dc in the next 3 stitches* repeat from * to *  until you are left with 4 stitches. Then dc in next 3 stitches and  end with 2dc in the last stitch. (120)


Row3: repeat Row 2 in C1.

Row4-6: Repeat row 2 C2.

Row7-9: Repeat Row2 in C3.

Row10-12: Repeat Row2 in C1.

Repeat Rows 4-12 desired number of times. I repeated 7 more times.
