Crochet Simple Sea Glass Baby Blanket Pattern

This simple sea glass baby blanket was such a joy to crochet. Creating this blanket has been an absolute delight, thanks to its uncomplicated yet repetitive stitch pattern. It provides the perfect opportunity for your mind to wander freely as your hands work their magic.

A great project to do while hanging out with the family.

When you have a beautiful textured fabric created with basic stitches that you can work without thinking too much, it is a truly restorative and meditative experience. The chosen colors, reminiscent of sea glass, add an extra layer of charm. I hope this crochet project piece brings you as much joy as it has brought me.

This free crochet pattern uses such a soft and cozy yarn that works up really beautifully. It may look a bit heavy, but it has a nice drape. I like the way the blanket turned out so nice and even. No need to block it. This will make a great baby shower gift.

Baby Blanket Sizes

This blanket is 28 X 33 inches, which is close to a square blanket. It’s just the right size for a baby blanket, toddler blanket, or Lapghan.

If you are ready to make this your next crochet project, we have a comprehensive guide on standard blanket sizes.

Below is an excerpt to help you determine what size you want to make and how many chains you may consider starting with. Along with the amounts of yarn you should plan on using, depending on the stitch patterns you choose.

• Lovey blanket 20 x 20 inches. Starting chain will be about 65-75 chain stitches. Plan on about 300 yards of yarn.

Straight Box Stitch Baby Blanket Pattern

This easy project uses the straight box stitch, which uses the chain stitch, single crochet, and the double crochet stitch worked in clusters. It’s a great blanket for beginners and works up quickly.

While you can use different edging options, I used the straight box stitch on the edging too. It turned out quite nicely and softened the edge. The finished product resembles the shell stitch.

Medium Weight Yarn

I love the way this stitch looks with this yarn and I’m excited to keep experimenting with different stitches. Thank you to our friends at Furls for sending us this Wander Acrylic Yarn to try! It is a number 4 medium yarn weight.

While acrylic yarn is the most popular synthetic fiber on the market (TL Yarn Crafts), this would work well with a soft bamboo or cotton yarn too.

This pattern uses three yarn colors Agave, Patina, and Wintermint, which makes this a lovely baby blanket for a little boy. The colors change every other row creating simple stripes. Since the yarn is carried up the sides of the yarn, it is super easy to crochet. Add two rows of the straight box stitch around the outside for an uncomplicated, yet beautiful border that looks like shell stitches.

This Wander yarn comes in many colors, and you can change the color scheme for a little girl baby blanket.

Video Tutorial and Photo Tutorial

This modern crochet blanket pattern comes with a video tutorial for both right hand and left hand crocheters. There are a few photos to help you with the stitches; however, you can find a step-by-step photo tutorial along with the video links on How to Crochet the Straight Box Stitch Tutorial.

There are video links at the bottom of this crochet pattern showing how to carry the yarn up the side and crochet the border.

Crochet Pattern Notes

Turn at the end of each row.

The chain two at the beginning of each row counts as a double crochet. Alternatively, you can work a chain three if you want less height.

Another alternative to this pattern is when working the single crochet and chain two for each cluster of stitches. You could work a slip stitch and chain three. 

You will be working a series of crochet stitches around the chain stitches in the row below that was created by the CH 2. Once you get going, this is a nice crochet project to do if you don’t want a lot of counting.

Row 2 to pattern repeat throughout the pattern.

The color changes every other row. Carry colors up the side of your work, do not fasten off at the end of each row.

This pattern is written in U.S. crochet terms and abbreviations.

Using the Agave color yarn.

Work a foundation chain of 88.

Skip the first 3 CH STs (This counts as a DC). Work 3 DC in 4th chain from hook. [SK 3 CH STs in the 4^th CH ST work (SC, CH 2, 3 DC all in the same ST). Repeat between [ ] to the last 4 CH STs. SK 3 CH STs, and work a SC in the last ST at the end of the row. Turn

Row 2

Continue to repeat row 2 until desired length.

Every other row, change the yarn color.

Continue alternating this color pattern until you reach your desired length.

I ended on two rows of Agave.

Skip to the next SC SP and work the straight box stitch cluster. When you get to the bottom row, I worked the straight box stitch cluster into the same CH ST where the stitches were worked in the first row. Join with a SL ST. Turn

Row 2

CH 1 (Does not count as a ST). Work the (SC, CH 2, 3 DC) same SP. Skip to the next CH-2 SPand work the straight box stitch cluster. Continue working this cluster all the way around. Join with a SL ST.
