Last year we added a new baby to our extended family! My brother and his wife had a baby girl.  As soon as I found out my sister-in-law was expecting, I started bugging them about baby quilt designs. I mean, of course, I’m making a quilt for that new baby!

While talking to my brother about what he liked regarding quilting designs and colors, we kept returning to a simple herringbone pattern. I was up for making something more intricate, but my brother and his wife have a simple modern style, and the herringbone pattern seemed like it would blend into their nursery design perfectly.

We settled on using solid fabrics for the front of the quilt then he asked me if I had any elephant fabric for the back.

I had to laugh because, YES, I have elephant fabric. My Safari Party fabric line had a print with rows of mama and baby elephants. I was so excited that I could use the print in the quilt.

Simple Herringbone Quilt Pattern

At first, I wasn’t going to write a tutorial for this quilt, show photos, and give some general dimensions. Then I remembered what happened the last time I did that and didn’t want a million emails again asking for specific directions, LOL!

Before I share the tutorial, know I did not “invent” a herringbone quilt pattern. It’s been around for AGES.  I’m not claiming that I invented it.  I’m just sharing how I made this quilt in case you want to make one yourself.

For this quilt, you need 54 Half Square Triangles (HST). I’m going to show you how to make 8 Half Square Triangles at a time, saving you LOADS of time while making this baby quilt.

Baby Quilt Dimensions: 36″ x 54″

The Half Square Triangles in this quilt are 6″ x 6″ finished (which means they are 6 1/2″ x 6 1/2″ before they are sewn into the quilt). You can make the quilt bigger by making more blocks; you’ll have to do a bit of math.

Quilt Supplies

Assuming 40″ of useable fabric width

Cutting Directions

  • 7 pieces from Fabric A 13.75×13.75
  • 7 pieces from Fabric B 13.75×13.75

How to Make 8 Half-Square Triangles at One Time

Step One Mark the Fabric:

On all of the lightest pieces of fabric, draw an X diagonally on the wrong side of the fabric.

Step Two Pin:

Pin one marked fabric square with one fabric square from a 2nd fabric, right sides facing.

Step Three Sew:

Ensure you know where the 1/4″ seam mark is on your sewing machine foot. For these steps, it’s important to stitch exactly 1/4″ on each side of the line.

Stitch 1/4″ on each side of the line you drew in both directions.

Step Four Cut:

You are now ready to cut your square into eight smaller pieces. To do this, you will make four cuts using your rotary cutter and quilt ruler.

First, cut a line horizontally across your block exactly in the center. Next, make a vertical cut also in the center.

The last cuts are made diagonally along the line that you drew in step one.

Step Five Press & Trim:

You should now have 8 pieces of fabric.  Open up the HST’s and press the seam towards the darker fabric.

Trim up each sewn HST to 6 1/2″ x 6 1/2″. I like to use a Bloc-Loc ruler to trim and square up my HST’s.

How to Assemble the Quilt Top

There are dozens of ways to stitch half-square triangles together to create patterns in quilts. You can create chevrons, triangles, stars, pinwheels, and so many other patterns. The herringbone pattern created in this quilt is made by arranging the triangles in such a way to create a herringbone pattern.

Normally I like to stitch my quilts together in rows; for this quilt, I think it’s easier to stitch it together by column.

Follow the diagram below to arrange the HST’s in the quilt. There are 9 HST’s in each column of the quilt.

After you’ve sewn 6 columns of HSTs together, you will stitch the columns to each other. Again following the diagram directions.

Quilt and bind as desired. To quilt my quilt, I just quilted straight lines 1″ apart using my BERNINA and walking foot.

So many cute baby quilts can be made using just Half Square Triangles. If you like this pattern, you may love this baby quilt pattern with six different layout options.

  1. So simple and yet oh so pretty! Thanks for the tutorial! Does this way of making HSTs produce all on the bias, like when you sew around the edges of the squares to make 4 at a time?

  2. Thanks for this post! I’ve always wanted to make this, and you’ve given me just the nudge I needed!

  3. Will this be horribly off if I measure and hand cut these out without the rulers/cutting mats? I’m a perfectionist and while I’d love to have all that, it’ll be awhile before I’m able to get those so I’m trying to get over the “it has to be perfectly square” unless it actually needs to be perfectly square lol

  4. What was the purpose of this post if you’re not giving specifics? I don’t know what to do after the 13.75 cuts and you’re not giving specifics because you don’t want questions? Sheesh

  5. Beautiful and easy to understand. Thank you. I want to try this for a basinet with the scraps I used to make sheets.

  6. Hi- I’m new to quilting and decided to start so that I could make a blanket for my soon to be niece. I have a gifting etiquette question, should you wash the quilt before gifting? Since this is for a baby I have a strong inclination to wash first to get rid of all the starch and spray basting but on the other hand I love how crisp it looks and worry it won’t look fresh and new if washed (totally superficial reason!). Do you ever attempt to press a quilt after washing or do you embrace this cozier aspect of a quilt and let the crinkles reign supreme?

    1. It’s totally up to you and there is not really a right answer. I don’t wash mine, unless I feel like it got excessively handled or my machine quilting looks bad and a good wash and dry will make it nice and crinkly! If you do wash it, just included a note “washed and ready for use”. I’d also use a baby-friendly detergent like Dreft.

  7. Is it me or does the fabric seam off.

    If I’m am to cut 7-13.75” that’s 3 per width of the fabric, so that’s 3 cuts or 41.25” or 1 1/4 yds.

    I haven’t made it just yet, but bought supplies and now I’m kinda messed up and ver bought fabric…arg.

    1. If you notice, the pattern says “assuming 40″ of useable fabric width”. Not all fabric purchased has 42 useable inches. Some have very large selvage edges. In that case you would only be able to get 2 squares per cut.

  8. I love this tutorial! Thank you for such awesome instructions! I am new to quilting and have made a quilt for 3 of my granddaughters, each one I’ve tried a new skill. This pattern will be perfect for a quilt for one of my grandsons! I already have the fabric picked out!

  9. Hi Melissa. Just adore your Herringbone Baby Quilt. My daughter saw this and has asked me to make her one (she is a baby no longer but a full grown adult). Could you please tell me what measurements and size I would need to make for a King Size quilt if you could please.

  10. Making this quilt now! Maybe it’s my math but the 13.75” big square size seems a smidge too small to use 1/4” seam spacing and be left with 6 1/2”… 13.75/2 = 6 7/8…. Subtract 1/4 * 2 for the amount you lose to the seam on each triangle half: 6 7/8 – 1/4 – 1/4 = 6 3/8”. That leaves you about 1/8” short of being able to make the 6 1/2” HST size, and that’s if everything is perfect. I had to tighten up my seams to 1/8” once I realized this. Am I thinking of this wrong or should be big squares be at least 13 7/8, or 14 for some wiggle room/imperfection?

    1. You don’t subtract 1/2″ from the measurement, I think that’s where your math is off. Think of it as creating individual blocks. 13.75 x 2 = 6.875 minus the 1/4″ seam = 6.625 leaving you enough fabric to trim and square up to 6 1/2″ as noted in the pattern. The pieces are 6 1/2″ before finishing, and are 6″ FINISHED blocks. The 6″ is after they are sewn into the quilt.
      But there is no harm in cutting your first squares 14″ if you prefer that method.
