Diamonds and Purls Baby Blanket Knitting Pattern

Every spring and summer I go a little baby blanket crazy. Since there’s not much need for toques, mittens, and scarves, I take this time to come up with as many baby blanket designs as I can. I’m so obsessed with baby blankets because they are simple, repetitive, and low stress. Plus, there’s never a shortage of babies to gift them to! And if I really love a stitch, its so easy to modify the pattern to make a throw or scarf later.

This baby blanket is made by combining knits and purls to create a gorgeous diamond stitch. The end result is a baby blanket that not only looks elegant, but is also light weight and soft – perfect to cuddle up with in the warmer months.

The stitch may look tricky, but once you get into a rhythm, this blanket is so much fun! It was one of those blankets that I didn’t want to end because I just really enjoyed getting lost in my knitting and zoning out the world around me.

I have written out and posted the free pattern for the Diamonds and Purls Baby Blanket below on this page.

  1. Oh I love this pattern also. Can you tell me what kind of yarn you used. I just finished the one you used Paintbox yarn in lavender color even though it was called something blue and white. I made it for my new great granddaughter and now I want to do this one. Love your patterns. Thanks for sharing your beautiful work.


    1. Hi Linda! You’re welcome! I’m so glad to hear that you enjoyed the pattern! The yarn that I used is Knit Picks Mighty Stitch. The link is in the list of materials above on this page 🙂

  2. Oh this is smashing….great name you chose and to add to it I will be seeing tiny pearls on it…..What I love is the edging as well. Thank you so much. I am buying the pattern as its easier to negotiate without all those horrid ads..

    1. You are so welcome Sue! Thank you so much for purchasing the pattern too! The income from pattern sales goes towards maintaining the website and allows me to pay myself a bit too so that I can continue to make patterns and create inspiration for knitters and crocheters.

  3. I love this blanket. It iz do pretty and delicate looking. I am making this for a dog. She loves her blankets. My question is i need to make it wider. I want it to be 40 by 50 inches wide. I need to know how many stitches to cast on and the extra stitches to make it wider. I am think of doing it in a yellow color.

    1. OMG that is so adorable, I love that your dog loves blankets! Use a multiple of 9 plus however many you would like for the border.

  4. Hi Alnaar, Love this pattern. Could you please tell me the multiple so I can make this lovely blanket bigger? I save all of your patterns as they are so beautiful.

  5. This is such a pretty blanket! Do you think it would look nice in variegated yarn? Or do you think it would be better to stick to solids? Thank you so much for creating and sharing this lovey pattern!

    1. You’re welcome Ashley! For this one I would stick with a solid color to make the diamonds the focus and not the changing yarn color.

  6. The link to the yarn won’t open and I don’t want to assume anything when buying the yarn. Please confirm that the yarn IS NOT bulky or super bulky. When this blanket appeared in my feed I saved it hoping that there would be a baby in the future and this past weekend I learned that we’ll have a new addition. This is a lovely and gentle pattern. Thank you.

  7. Hi
    I would love to knit this for my new grandchild who is due in November can you tell me if it’s DK yarn or Aran
    Its a beautiful blanket it will make a wonderful heirloom.
    Regards Adele

  8. Lovely pattern. Would it work to ‘slip’ first stitch for the side edges? Did you blanket stitch outside edge? Thank you, progressing knitter here!!

  9. Love this pattern, & I’m making it for new granddaughter in October. I’m using Baby Bee soft & sleek, its not verigated but has spots of baby colors. Turning out sooooo pretty, thanks for this beautiful pattern

  10. Can you knit this to double knit as I’ve started to and think the knitting needles are to big ,I’ve got a lovely shade of pink ,my daughter is having her baby girl in January our first granddaughter

  11. Thank you for sharing this pattern, I finished this for friends first grand baby in pistachio. It knitted up beautifully, instructions were easy to follow and the finished product was gorgeous.

    1. Hi Maria, you need to cast on a multiple of 9 Plus however many you would like for the border. In this case the border is 2 knit stitches on each end, which is a total of 4 stitches (117 + 4 = 121).
