This Sea Glass crochet afghan pattern uses a simple two-row stitch repeat to create a pretty textured blanket with rows of colorful stitches and open spaces. The easy, repetitive pattern lets your mind wander as you work … so restorative and meditative!
I absolutely love the combination of blues, turquoise, and purple I used for this blanket. The colors remind me so much of pieces of sea glass washed ashore, which is exactly how this afghan got its name.
The pattern is worked in straight rows with no increases or decreases, and the colors are carried up the side as you work. You can also easily customize the width and length to make the blanket just the size you want.

Such a lovely blanket, and clear pattern to follow! It seems like my blanket it’a getting wider as I go on though!
Did you get a reply regarding your concern? Mine is not square either and I’m about 23″ done. I think I’ll rip it and find a better pattern.
Hi Marj 🙂 what are you looking for a response about? The numbers of rows? It should be 155 rows
You should have 76 single crochet and 75 ch2 spaces on every row that starts with a single crochet.
And 152 double crochet on the rows that have double crochet stitches.
Your afghan should not be getting bigger, unless you are adding stitches by accident or your tension is too loose.
thank you for the pattern I love it ! Here is my finished afghan

I really love this pattern. I’m doing it in the same colors as a baby blanket for a little boy. I think I will do a pink one next. Thank you for the wonderful graph. That really helped. Happy hookin y’all.
I love the colors. Please, if I wanted to make a smaller blanket, what is the stitch count?
I found this pattern after work and felt I had to try it immediately. Only problem I had with it was I kept trying to put double crochet inn where the single crochet stitches belonged. I guess I was more tired than I thought.
Hi. I love this pattern. My sister loves sea glass and she just bought a new house and decorated it all in sea glass type colors so I figured this be perfect for her. But I have a question: I’m about 40 rows in and the blanket’s not even close to being 73 inches. My width was a little short too so I figured my stitches must be tighter than yours so I gradually loosened up my grip. I bought all the yarn you suggested so I was trying to figure out how long the blanket should be before adding the border so I don’t run out. Is your count of 55 rows maybe just the double crochet rows?
Thanks.
Hi Amanda 🙂 You are correct. It should say 155 rows, not 55 rows. I have corrected it now … sorry for the typo and confusion!!
Excellent! That makes do much more sense. Thank you!

I love the combination color of this blanket. Thank you for sharing the pattern.
Thank you 🙂
I finished it! A Seattle Seahawks inspired blanket for my daughter’s school art raffle. LOVE the pattern (even my husband likes the finished project!). Wish I could post a picture. Thanks for the pattern. I will use it many times in the future.
I don’t know if you can help but my edges are not straight. When looking at it the edges angleing – so it is not square. – but each row has the exact same # of stitches. Can’t figure out what I’m doing wrong – any ideas?? Thanks
Hi Kim 🙂 I’m not really sure why the edges seem off, especially since you have the correct number of stitches for each row. The only thing I can think is that perhaps you aren’t working the last single crochet of one row into the top of the beginning chain of the previous row. Either way though, when you add your edging it should smooth things out. Hope that helps.
