In honor of my Grandma who made me my Sunny Ripple Afghan 30 some years ago. Here is my interpretation of the pattern in crochet.
Crochet hook size G
Several colors of soft 4 ply worsted yarn (about 20 oz yarn total)
Baby Sized - Chain 152
ROW 1: 2 sc into 2nd ch from the hook. *Sc into next 10 ch, skip 2, sc into each of next 10 chs, 3 sc into next ch, repeat from * 8 more times. Sc in next 10 ch, skip 2, sc in next 10 ch, 2 sc in last ch. Ch 1, turn. (RIGHT SIDE)
Row 2: from now on sc in the back loop of each stitch. 2 sc in first sc, *sc in each of next 10 sc, skip 2 sc, sc in next 10 sc, 3 sc in next sc (which should be the middle of the 3 sc of row 1). Repeat from * 8 more times. Then sc in next 10 sc, skip 2, sc in next 10 sc, 2 sc in last sc, ch 1 and turn. Repeat row 2 for the entire afghan.
Repeat Row 2 throughout. Finished blanket should measure about 4' long or desired length. Change colors after every 4 rows or so. This is a very flexible pattern.
I have seen ripples with color changes mid-row.... just depends on the look you want.
