These instruction are written directions for more experienced crocheters. A photo tutorial for beginners and those not experienced with ripple crochet will be completed shortly.

To make this project, I use worsted weight scraps that range in length from 8″ (usually longer) to 2′. I tie them end-to-end using a square knot and leave a tail of at least 1/2″.

At the bottom of the page, there is a video I made that demonstrates how I do this.

WRITTEN DIRECTIONS:

Materials:

5.5 mm crochet hook.
Lots of yarn scraps of a similar weight and fiber
A piece of paper and pencil to do a very little bit of math

Beginning with Row 2 the stitches of the the afghan are worked in back loops only (except for the last stitch of each row which is worked though both loops). This creates the visually iconic ridge. Two rows of single crochet form one ridge.

Foundation chain with longer scraps (18 to 36 inches): A multiple of 13 + 12

To make my afghan, I decided I wanted 17 downward “points” so I calculated the foundation chain as follows

17 (13) + 12 = 233

Row 1: Working through back ridge loop, sc in 2nd ch from hook and in next 4 chs; *3 sc in next ch; sc in next 5 chs, sk next 2 chs, sc in next 5 chs; rep from * to last 6 chs; 3 sc in next ch, sc in last 5 chs. Ch 1, turn.

Row 2: Sk first sc *working in BLO, sc in next 5 sc, 3 sc in next sc; sc in next 5 sc, sk next 2 sc; rep from * to last 12 sc; sc in next 5 sc, 3 sc in next sc; sc in next 4 sc, sk next sc, sc through BOTH LOOPS of last sc. Ch 1, turn.

Repeat Row 2 until the afghan is the length you want.

FOR BEGINNERS AND CROCHETERS NEW TO THE WONDERS OF RIPPLE CROCHET PATTERNS:

To calculate the number of stitches in your foundation chain you take the number of times you want the pattern to repeat (for the purposes of the tutorial, I did 1), multiply by 13, and then add 12.

1(13) + 12 = 25

Next using a worsted weight yarn and a 5.5 mm (or I) hook, chain 25:
