A Few Things to Know Before You Start

Before you dive into the pattern, here are a few helpful details that will make your project even more enjoyable.

Yarn Changes Made Simple

This blanket uses two colors that are changed every other row. This creates a soft striped effect that adds interest without taking away from the delicate shell design.

A Better Starting Row for Cleaner Edges

One improvement I made to this pattern was reworking the starting row slightly. Traditional starting rows can sometimes leave gaps, which makes adding a border more difficult later on.

By adjusting this row, the edge becomes more stable and even—giving you a much cleaner finish when you add your border.

Therefore, it was trial and error quite a few times along with counting numerous times to develop this pattern that has a lovely crochet edge all the way around.

Finally, I had a swatch that was ticking all the things I needed. The yellow and white crochet swatch below shows the how I fixed the beginning rows. This pattern starts with the no chain double crochet and the first row after that begins with the shell stitch. It works!

Color Combinations to Try

This pattern looks beautiful in so many color combinations. Here are a few ideas to inspire your next project:

• Soft pink and white for a classic baby blanket
• Cream and taupe for a warm farmhouse style
• Light blue and gray for a calm, modern look
• Pastel combinations for spring-inspired projects
• Ombre shades for a subtle gradient effect

Change the Size of the Throw Blanket

This blanket is fully customizable. You can easily adjust both the width and length to create anything from a baby blanket to a full-size throw.

Common Sizes:

• Baby: 30″ x 36″
• Lap: 36″ x 48″
• Throw: 48″ x 60″

If you are wondering about a different size, here is a bit of information to help you choose your ideal size. Crochet Guidelines for Standard Bed and Blanket Sizes. Make sure to save this for future reference.

Border Ideas

Finish your blanket with a border that matches your style:

• Simple single crochet for a clean look
• Double crochet for a slightly thicker edge
• Picot edging for a decorative touch
• Wide shell border to complement the pattern

---

Storage & Care Tips

• Store folded in a cool, dry place
• Wash according to yarn label instructions
• Lay flat to dry to maintain shape
• Avoid hanging to prevent stretching

---

Yarn Substitutions

You can use a variety of yarns for this project depending on the look you want:

• Acrylic yarn: Durable and easy care
• Cotton yarn: Lightweight with crisp stitch definition
• Blends: A balance of softness and structure

Keep in mind that softer yarns will give more drape, while firmer yarns will create more structure.

Carrying Yarn to Save Time

To reduce the number of yarn ends to weave in, I carried the yarn up the side instead of cutting it when changing yarn. Since the yarn changes every other row, this works beautifully—and your border will neatly cover the carried strands.

This is one of those small tricks that makes a big difference, especially on larger blankets.

Many folks that crochet do not enjoy weaving in the yarn ends. When changing colors every few rows, that can be a large number of yarn ends to weave in if you trim the yarn each time that the color is changed.

Not to mention…it also adds to the yardage of the crochet project as you will need to leave enough to weave in later.

I added a crochet edge onto this blanket and it covers up the yarn that is carried up the sides just perfectly. The Youtube video tutorials will show how to change color and carry the yarn too.

This is a beautiful blanket to make for any occasion.

Crochet Stitches Used

Chain Stitch (CH ST)

Begin the chain stitch by making a slip knot on the crochet hook. Leave about a 5-inch tail on the yarn. This will be weaved in later.

Next snug up the yarn loop that is on the crochet hook; while it should be firm, it should also be loose enough to slide on the hook with ease.

Keeping the loop on the hook, insert the hook in the stitch, wrap the yarn over the crochet hook from back to front. Draw the yarn through the loop. (The first chain stitch is complete).

Special Stitches used in this Handmade Baby Blanket:

V-Stitch: This consists of a DC, CH 2, DC in this crochet pattern. However, when this is worked on the ends, there are no Chain Stitches between the Double Crochet Stitches. This avoids the half fan from sticking out too far along the edge.

Shell Stitch: This consists of 8 DC in this crochet pattern.

Half Shell Stitch on the ends: When this is worked on the ends, there are two options for the number of DC in the half shells.

Pattern Notes

• Worked in rows
• Turn at the end of each row
• Beginning chain counts as a stitch where noted
• Stitch multiple: Multiple of 4 + 1

• In the yellow and white crochet blanket, I worked a CH 3 (counts as DC) and 3 DC.
• In the pink and white crochet blanket, I worked a CH 3 (counts as DC) and 4 DC.
• No matter which way I worked the blanket edge, I still inserted my hook between the 2^nd and 3^rd DC for the next row.
• This variation just provides a bit different look and both look lovely and timeless.

Carry the yarn up the sides of the blanket. Since there will be a crochet border on this blanket, it is the perfect crochet pattern to carry the yarn up the sides. This greatly reduced the need for weaving in yarn ends.

Crochet Pattern Directions

Beginning Row

I began both blankets with the white yarn.

Begin by making a slip knot on the crochet hook.

133 No chain double crochet. If you are not familiar with this stitch, there is a video just for this. However, this row is also included in the crochet tutorial for this pattern. Turn

Row 1

CH 1, SC in the Same ST. [SK 3 STs, work 8 DC in the 4^th ST, SK 3 STs, work SC in 4^th ST] Repeat between [ ] across until 4 STs left. SK 3 STs, work 2 SC in the last ST. Turn

For row 2 change color

Row 2

CH 3, DC in the Same ST. [CH 5, SK the 8 DC fan stitches, in the SC SP complete (DC, CH 2, DC)] repeat between [ ] across. End with 2 DC in the last ST. Turn

Row 3

CH 3, complete 3 or 4 DC (see half shell stitch edge options above) in the V-Stitch. [SK the first 4 DC in the Shell ST below, in between the 4^th and 5^th Shell ST below, work a SC.  (making sure to trap the previous row chain STs between the SC stitch to secure). SK the next 4 DC of the Shell ST below. Work 8 DC in the V-Stitch of the previous row.] Repeat between [ ] across. End with 4 or 5 DC in the final V-Stitch. Turn

For row 4, change back to the white yarn.

Row 4

CH 1, SC same ST. CH 5, SK the 3 or 4 DC. In the SC SP, work (DC, CH 2, DC). [CH 5, SK the 8 DC, work DC, CH 2, DC in the SC SP]. Repeat between [ ] across. At the end, in the last SC work the DC, CH 2, DC, then CH 5, SK the 3 or 4 DC. In the top CH of the CH 3, work 2 SC. Turn

Row 5

CH 1, SC in same ST. SK 2 DC, insert hook between the 2^nd and 3^rd DC of the previous row and complete a SC.  (making sure to trap the previous row chain STs between the SC stitch to secure). Work 8 DC in the V-Stitch of the previous row. [SK the first 4 DC in the Shell ST below, in between the 4^th and 5^th Shell ST below, work a SC.  (making sure to trap the previous row chain STs between the SC stitch to secure). Work 8 DC in the V-Stitch of the previous row.] Repeat between [ ] across. End with 8 DC in the final v-Stitch, SC between the 2nd and 3rd DC of the previous row. In the final stitch, complete 2 SC. Turn

For row 6, change back to the colored yarn and so on. Every other row, change the yarn color.

Rows 6 and beyond

Continue repeating rows 2-5

I made my crochet blankets 83 rows long. That is in addition to the no chain double crochet beginning row.

I ended with the row 3 stitch pattern. This made it easy to even out the edge and prepare for the crochet border.

Row 84 Final Row:

Using the white yarn for this row.

CH 1, SC in same ST. SC in the next 2 or 3 STs (depending on what you chose for your half shell on the end). DC in the next ST, TR in the SC, DC in the next ST. (The DC, TR, DC will be done each time there is the SC between the shells. Everything else in the last row gets a SC). End with 2 SC in the last ST.

Crochet Border

Continue with the white yarn for the border.

Round 1

SC in each ST around with 3 SC in each corner ST. (when working the sides, make sure to capture the yarn carried up the side when completing the SC. Also, just ease the SC STs on the sides so the SC looks even and does not pucker). End with SL ST into the first SC.

Round 2

CH 3, DC in each ST around with 3 DC in each corner ST. End with SL ST into the top CH of the first CH 3 STs.

Finishing

After you work the last ST, cut off the yarn leaving about a 12-inch long tail. Pull the yarn tail through the last loop on the hook.

Tips for Success

• Use stitch markers to keep track of pattern repeats
• Check your stitch count every few rows
• Keep your tension even for a consistent look
• Blocking your finished blanket will help open up the lace design

Is this pattern beginner-friendly?

It’s best suited for confident beginners ready to try an intermediate pattern.

Can I use a different yarn weight?

Yes, but it will change the size and drape. Adjust your hook accordingly.

Why does my blanket look uneven?

This is usually due to tension or missed stitches. Blocking will help even out the final piece.
