Methods to Conquer Half-Square Triangles (HSTs)

If you plan on diving into the world of quilting, you will soon run head first into half-square triangles, or HSTs in common quilting parlance.

These deceptively simple looking squares can be arranged innumerable ways to make an unending canvas of lovely. When you decide to tackle HSTs you are going to need figure out the best method for you. The most important thing to understand about HSTs is the math behind the size you want. This post does not cover that math. There are many, many charts available online to help you figure out what size triangles & squares to cut and sew in order to get the finished size you want.

Once you know your math, you’ll need to figure out your method. Here are a few to consider:

1. Tried and true

The most basic way for creating a HST is taking two squares of fabric, placing them right-sides-together (RST), drawing a line down the diagonal, and then sewing a scant ¼” on either side of the link. Cut the fabric along the center diagonal line, open and press.

Square that puppy up and before you know it…

…voilà, lovely HSTs, just for you.

Works best: when you need to only do a few HSTs or when each HST you need to do is unique.

2. Make the Magic 8

When I sewed these together both squares were evenly on top of each other.

As soon as you see the visual on this you’ll get why they call it magic. Take two large squares, right sides together and draw lines down each diagonal. Sew a scant ¼” on both sides of each line for a total of 4 seams.

Start by cutting first along the two diagonal lines.

(For this tutorial I placed the two squares off center to show you the two fabrics. When I sewed these together both squares were evenly on top of each other.)

Carefully start cutting. Start by cutting first along the two diagonal lines.

Next cut down the center line of each side of the square.

You’ll need to open, press, and square them up, but in no time flat you’ll have 8 lovely matching HSTs.

Works best: when you need more than a few. Some people can really churn out a lot of HSTs this way. If you have a bunch you need to make with the same fabrics, try this method.

3. Tube Method (Tube Quilting)

Use your ruler to cut out the size triangle you need.

Sew two long strips together on the top and bottom edges. Then use your ruler to cut out the size triangle you need. Here I’ve shown you the tube I sewed and the triangles I cut (I flipped the top triangles over to show you the contrasting fabric).

Works best: when you need multiples of the same type of HST, this method is a production machine!
Note: it really helps to have the exact sized ruler you’ll need for cutting out the triangles.

4. Sewn Strips (Bias Strips)

Create a massive amount of HSTs in a short time!

I found this the most challenging of all the techniques I’ve tried, but I’ve never been pro at cutting on the bias. There is incredible potential here, however, to create a massive amount of HSTs in a short time so I’m keeping this method tucked away for the next time I want to attempt it.

The concept is simple: take two large pieces of fabric and place them RST. Cut the fabric into bias strips (in the correct size you’ll need) and then sew the alternating colors together to create two pieces of fabric with bias strips in the colors you need.

If you did your math right, you can then cut strips of fabric that will have the HSTs already sewn together. As you can see above, I completely botched the math on this, but you live and you learn and like I said, POTENTIAL. This method has so much potential if I can just get right next time.

Works Best: when you need to make HSTs on a massive scale.
Note: take your time to get the measurements just right. If not, you’ll have a whole lot of messed up fabric on your hands. Additionally, there is fabric waste as you cut out the squares. Make sure to account for that when you buy the amount you may need.

5. Jenny Doan Method (Sew the Square)

I’m not sure if this method has an official name but I know it has become popularized by Jenny Doan of the Missouri Quilt Company. I consider this a cousin to the Magic 8 method. Perhaps we could even call it the Magic 4.

The Magic 4!

Take two pieces of fabric RST and sew a scant ¼” hem all the way around.

Carefully cut down the diagonals of the square and you’ll get four perfect HSTs.

You get four perfect HSTs.

Works best: this is a quick and easy method that could be easily mass produced especially when using pre-cuts.
Note: some don’t like this method means you are working on the bias. I haven’t found this to be a problem. Press carefully when you iron sew your HSTs together, without unnecessary stress or tugging, and you’ll be fine.

I hope you’ve found these methods useful. How about you? Do you use one of these methods already or do you have a different technique you prefer? Let us know in the comments!

Learning & Re-Learning

Generally speaking, I can be more of a hand-sewer than a machine-sewer. Getting frustrated with a machine, to me, isn’t the most difficult task, so stepping back from one can be a fairly easy decision. What I’ve found in stepping away is that I actually like hand-sewing. Sure, the process might take longer, but there’s something relaxing about going one stitch at a time with my own hands.

And, believe it or not, I might actually be more likely to sew a straight-ish line by hand than I am with a machine! Weird? Maybe!

But stepping away from the machine has led to me trying to re-acquaint myself with my sewing machine, and what I found is that the time away caused me to potentially forget things—maybe keep me from fully learning all things—about my machine. Had I had (or kept) those things in mind, I suspect my sewing-machine-experiences might’ve gone a bit better—and a bit quicker.

Now, don’t get me wrong! I’ve completed projects on my sewing machine. But I was potentially setting myself up for frustration by not really understanding or memorizing the details of this machine (Brother LX2500):

Imagine how far I could be with machine-sewing if I would’ve taken the time to learn more details and commit them to memory! So, for today, I’m going to give you that bit of information: Get to know your sewing machine! Even something as simple as realizing the thread-holder lifts higher could prevent grief, since you might not have as much issue with the thread falling off while you’re sewing or threading your bobbin. And, yes! That happened to me!

For me, figuring out the need-to-know details and letting the rest go might’ve been tempting. Do yourself a favor, and don’t keep that thought process. There might be aspects of your machine that make for easier sewing, or that advance your capabilities in a way that a basic “Hey! I can thread the needle and bobbin!” don’t quite cover. Possible examples: Apparently, I have a reverse button on my machine I maybe never knew about, and a way to alter the tension. Who knew?! And if you don’t get to know your machine, by the way, don’t be surprised if you come out with stitches that look like these:

If you buy your sewing machine brand new, check out any instruction manual that comes with it. The reading might seem tedious, but that tedious task could be worth it when you don’t hate your sewing machine, like, twelve times per use (Am I exaggerating??? You decide!). If you buy yours used, don’t have a manual, or lose the manual, try looking online. I think I threw mine away (don’t do that!), but luckily there are videos available on Youtube that show the basics of running my model. I can’t encourage you enough to look into such information to learn what you can about your sewing machine! Doing so could extend your possibilities and preserve your nerves!

Your sewing machine is only as good as your ability to use it, so don’t hold yourself back by not learning about it properly.

And even if you did know all there is to know about your machine, forgetting details after a limited amount of use isn’t out of the realm of possibility. Think about all the math classes you had over the years. Even though you might’ve had formulas in your head for a time—like, for an exam—how many do you still remember? After a while, your sewing machine’s details might be so burrowed into your thought process that you can be away for a time and remember them, but don’t be too embarrassed to rediscover those details if you can’t bring them to mind. Something like which way your bobbin’s thread goes could be so small that you don’t remember it, but not knowing could complicate your sewing.

So that’s lesson number two, one I had to learn when I came back to my sewing machine after time away: Don’t be afraid to admit you don’t remember, or be too proud to look into how to do these things again. Your sewing machine is only as good as your ability to use it, so don’t hold yourself back by not learning about it properly—even if it isn’t the first time you’re learning about it! Don’t stop until you know what every button, knob, or contraption does!
