1. Worsted weight (size 4) yarn in 4 colors. I used colors Aran and Arbor Rose from Loops & Threads Impeccable and colors Cool Blue and Soft Grey from Bernat Super Value
2. Hook I (5.5mm)
3. Yarn needle to weave in the ends

Finished Size
The afghan is 34 inches wide and 37 inches long before adding the squares.

410 yards of each color.

Each peak measures 4 1/4 inches wide

Stitch Abbreviations
The pattern is in standard American terms.
sc- single crochet
hdc- half double crochet
dc-double crochet
tr- triple crochet
sl st- slip stitch
ch- chain
st- stitch
YO- Yarn over

1. To increase the width of your blanket add chains in multiples of 36. Each 36 chains will add around 8 inches to the width of your blanket.

2. When skipping your chains after making a peak, make sure you are not missing the one squished at the base of the previous st.

Row 1: With cream color yarn, ch 144, work into the back bumps of the chain throughout this row, 3 dc in 5th ch from hook, *[sk 2 chs,  3 dc in next, sk 2 chs, (3 dc, ch 3 and 3dc) in next ch to form a peak, sk 2 chs, 3 dc in next, sk 2 chs, 3 dc in next, sk 5 chs, 3 dc in next], repeat from * until you have 1 ch left, 1 dc in last ch, turn.—— 8 peaks

The 3rd row is worked in a contrasting color to show how the stitches are stacked

Row 2: Ch 4, work 3 dc in the gap between the first two 3 dc groups, 3 dc in next gap, (3dc, ch3, 3dc) into the ch-3 space at the peak, *[3 dc in next 2 gaps, sk the next big gap between the 3 dc groups forming the valley and work 3 dc into the next gap, 3 dc into the next gap once again, (3dc, ch3, 3dc) into the next ch-3 space at the peak], repeat from * to the last ch-3 space at the peak, 3 dc in next 2 gaps, sk 3 dc and 1 ch, 1 dc on top of beginning ch-3, turn.———-8 peaks

Repeat Row 2 changing colors every 3 rows. Fasten off every time you change colors. To join the new color at the end of your rows, start working the dc and when you have 2 loops on your hook, yarn over and pull through the new color to complete your dc. Then work the turning ch in the new color.

Keep repeating the pattern until you have 17 stripes. Weave in all the ends.

Granny Squares ( Make 15)

Note: I have written the pattern for the granny square as a photo tutorial to make the steps clearer.

Finished Size
Each side of the square is 3 inches long

Stitch Explanation
Puff Stitch: [YO, insert hook into the st or space indicated and pull up a tall loop about the height of a dc st] repeat a total of 3 times, YO and pull through all 7 loops on hook, ch 1 to close the puff st.

Crochet Pattern

1. Work over yarn tails to minimize weaving in later.
2. This is a picture tutorial as I thought it is best suited for a Granny square.

                                                                                Round 1

Ch 4 and sl st to the first ch to form a ch ring.

Ch 3 ( counts as first dc and ch 1), [dc, ch 1]11 times into the ch ringsl st to the top of beginning ch 2 while picking up the next color. ———12 dc in the round

Round 2

Sl st to the next ch-1 space and pull up the loop on the hook to the height of a dc.

[YO, insert hook into the same ch-1 space and pull up a loop]twice, YO and pull through all the loops on hook,ch 2.

Puff st in next ch-1 space, ch 1, 1 tr in next dc, ch 1.

[*(1 Puff st in next ch-1 space, ch 1), repeat from * two more times, 1 tr in next dc, ch 1].

Repeat the steps within [  ], 2 more times. 1 puff st in last ch-1 space between the last dc and beginning ch-2, sl st to the top of the first puff st, picking up the gray color yarn.

Round 3

Ch 1 with gray yarn, 1 hdc in same st as ch 1, 1 hdc in next ch-1 space. Work 2 hdc in each ch-space and 3 hdc on top of each tr, do not sl st at end of the round.

Cut the yarn and pull the yarn tail out, thread a yarn needle with the tail and insert it under the first sc and then into the first st to form a fake st ( shown in blue below). Weave in the rest of the tail.

Square completed

Sewing the Squares onto the Ripple Afghan

Cream(Aran) color yarn is used to sew the squares onto the blanket on the wrong side. Keep both the blanket and the square with the wrong side facing up, place the square in one of the valleys at the edge, insert the yarn needle under both the loops of the blanket and only the back loop of the square, whip stitch them together along 2 sides of the square.

Tassels (Make 15)

Cut a piece of cardboard 4 1/4 inches long and 2 inches wide. Wrap the blue color yarn around the cardboard 13 times.

Pull an 18-inch piece of yarn through the winding and knot twice at the top.

Cut the yarn along the opposite side.

Take another 12-inch piece of yarn and tie a knot a little below the top knot.

Trim the tassel to level the edges. Use the 2 strands of yarn at the top to sew the tassel at the corners of the squares. The remaining yarn tail can be pulled into the tassel and trimmed to blend in with the rest of the tassel.

Hello! I’ve been looking for an airy ripple pattern to make so I can retire the one my Nana made for me in 1976. This looks awesome and I think it will fill the bill for me! What sold me were the diamonds. I collect peacocks and my 5 colors run the gamut of light teal to navy blue with gold to make “eyes” along the way. I can see those diamonds having a gold center with the navy border and maybe the light teal in between. Thank you for sharing! Dianna PS It’s going to be a while before I even start it -way too many WIPs right now! But I have bookmarked your page and will return with pictures when I start it!

Thank you for this pattern. I am not a seasoned crocheter. When the blanket begins becoming bigger, the end of the rows of seem to just get bigger. Do I hae to start making a part that starts going up? The sides of my blanket are not straight. I chose this pattern because it is the easiest and most attractive of all the ones that I could find online. Can you help please?

Can you email me a picture, please? You must be adding stitches at the beginning or end.
