Half-square-triangle short-cuts and easy square-up

I have been making a LOT of half-square-triangle quilt blocks recently. Half-square-triangles (or HST's) are one of the greatest basic building blocks of traditional quilting. I'm not a super-duper-precise piecer, but I am a firm believer in squaring-up blocks - especially half-square-triangle blocks. 
It just makes the piecing come together easier and look so much nicer in the end. 
But as we all know, the square-ing up process can get kind of tedious. Right? So I thought I'd share a trick I finally just discovered that has made the work SO much easier and faster. Oh my goodness, I don't know why this took me so long to figure out. Many of you are probably already doing this, but just in case you're like me, here's the scoop:
First of all, this is my favorite basic method for making HST's: Match two squares right-sides-together and draw a diagonal line down the back of one side. Sew a 1/4" seam on both sides of the drawn line. Cut on the drawn line. This will create two HST blocks. I generally like to make my blocks slightly larger than the final size so that I can have room to square them up. If you are making a bunch at once - especially if you are chain-piecing them - it's really easy for seams or matched-up squares to get slightly distorted. Here is the traditional way to square-up a half-square-triangle block.
This Quilt in a Day Square up Ruler makes the process SO MUCH faster. I've seen this ruler multiple times in shops, in my mom's sewing room, etc. and always wondered what it did, but never bothered to find out. Well I finally did and it's genius. The ruler is marked from one corner with traditional inchmarks divided into eigths. From the opposite corner it's marked in half-inch lines.
Before you even open the HST block, lay the corner of the ruler on top of the pieced block and match up the marking for the desired finished size of the block, right on the seam. (So for example, I want a 3" finished block, so I am laying the 3" line on my seam, NOT the 3" line on the bottom edge of the triangle.)
Trim two edges using a rotary cutter. By laying the mark on the seam you get a square block with the diagonal seam centered when you open up the block.
I then use my rotary cutter to trim off the ends so that I won't have the little triangle tags when I open up the block. 
And voila - a perfectly squared-up 3" HST block with no tags sticking out at the ends. Before you open up the block, press along the seam to "set the seam." Then press the block from the front, careful not to pull or distort the diagonal seam, using the tip of the iron right on the seam to make sure it is fully opened and flat. Makes the blocks so nice and crisp and the best part is that I can get through a stack of them so much more quickly. I suggest doing the whole stack one step at a time. (For example: sew all blocks, trim all blocks, and then press all blocks, to streamline the process.)

I traditionally press my seams to the side - usually the dark. Sometime though I'll press my seams open, especially if the blocks are small.
Here's a repeat of the process again, this time making my block a 2 3/4" block. Notice the arrow in the top left picture where I have lined up the 2 3/4" markings with the seam. Trim two sides, open and press. (Ruler in bottom right photo only to show finished dimensions.)
I know there are a lot of quilty-gadgets out there, and you don't need every one, but if you make a lot of HST's and dislike the squaring-up part, Quilt in a Day Square up Ruler  is worth it. (I know they are available also at JoAnn's and from the Quilt in a Day site.) I now use it ALL the time.
If you're looking for more half-square-triangle inspiration, here are a few other projects I've used them in: Half-Square-Triangle spectrum quilt,

  23. Love the ruler tip--I had not seen that before and turning a block 4 times (even with a turning cutting mat) is a pain. Also love that you can spell voila!! I can't stand seeing WA LA!!

    1. Haha! (I know right?!) Thanks. I'm glad that taking 5 years of French has helped me in some small way. ;) Because to be honest, I don't use it (or remember) much else.

  24. Your quilts are beautiful!!! I have that ruler and love it!

  25. An even better tool is the BlocLoc ruler. It has a groove in the back to hug your seam - it is fabulous!

    ReplyDelete
  26. That's genius! I've never seen that ruler before but will be asking for it at my LQS. And I have a HST project in mind to try it out. Thanks for the tip.

    ReplyDelete
  27. Thanks for the great tip! Now I can look forward to doing some half-square triangles.

    ReplyDelete
  28. HSTs are one of my favorite blocks. I was using the traditional method for squaring up, but this is pretty genius. Thanks for sharing Amy!!

    ReplyDelete
  29. It's funny... This week I also posted about how to make HST's using the Quilt in a Day ruler. It sure does make the process faster! Love your quilts.

    ReplyDelete
  30. I have a stack of triangles that I've been afraid to touch. This will definitely be helpful in making it as painless as possible!

    ReplyDelete
  31. I too have seen the ruler and never bothered to figure out how to use it. Good thing tomorrow is Saturday and I have some Joann's coupons! Thanks for sharing

    ReplyDelete
  32. This is a GREAT tut and I even own one of those rulers (but didn't know how to use it)! Thx so much! Being a newbie, it's great to learn all these neat tips! The whole squaring up a block thing is kinda mystifying to me as it is!

    ReplyDelete
  33. THANK YOU SO MUCH for this revelation! I'm in process of construction of a quilt using over 200 HSTs and this tip has come in time to save me a lot of frustration!!!!

    ReplyDelete
  34. I shall add this to my collection of HST tips, but really, one of these days I'm hoping the HST fairy will just show up here...

    ReplyDelete
  35. Glad to know about this ruler and method. I make a lot of HST too. Did you press to the side or open?

    ReplyDelete
    Replies
    1. Good question. I typically press to the side. (I'm just traditional that way.) But occasionally I'll press open, depending on how intricate the block is (i.e. how many seams there are) or how small the triangle is.

      Delete
  36. I have this ruler and have always just used it as a square--duh...
    This makes so much sense. I;m glad that you press to set the seam--so very few people do this and it is really critical.
