I have been making half square triangles like a mad woman lately. I have a new pattern that I have designed and I am really excited about it.
I know I have been through the process of making HSTs several times, and today will do it one last time so I can refer back to this post for future patterns. Here’s a look at the current crop of HSTs. When I get this lap size quilt fully assembled and quilted, then I will share it and the table topper you’ll see coming up with my Easter tablescape. But first….
let’s do HSTs!
I use only Aurifil 50 wt thread for piecing. I love that it is thin and strong, and I believe it gives more precision to your work.
Start by cutting your squares to at least 3/8″ (and I do 1/2″) larger than you want the finished HST to be. In other words, if you need the HSTs to be 2-1/2 inches for piecing the next step, cut the squares 2-7/8 to 3 inches square.
Draw a diagonal line from one corner to the opposite corner on your lighter color fabric.
Pair the two colors together. Many times this will be the focus fabric and the background fabric.
Sew 1/4″ away from the line on both sides.
Chain piece by setting up all your squares, then running them one after another through the machine. The chain makes sewing the seam on the other side really easy as they are all together. Just turn the chain around and sew 1/4 inch away from the other side of the line.
Cut the pieces apart from each other, then cut on the drawn line to yield two HST units.
Press toward the darker of the fabrics. Square up to the correct size, placing the 45-degree line along the diagonal seam and trimming all four sides.
That’s it! No need to be afraid of a lot of HSTs any longer. Quilts are so much more interesting with these angles as part of the design. Next time you see a pattern with a lot of HSTs, be confident, you can do it.
Update – I have discovered that my HST piecing is even more accurate if I mark the actual sewing lines. I use this quarter-inch ruler, lining up the line in the middle of the ruler with the corners, and marking the sewing line at a precise 1/4-inch. Sewing on the edge of the line nearest the center gives me a more accurate half-square triangle unit.
Happy Quilting!
I have loaded the Scrap Dance Quilt Along button on to my blog and checked. It works. When I get some time I will share my HST units on Flickr. Still have more to make.
Oh I just love chain piecing like this too!!! Glad the intimidation is dissolving!
Wowsers! You have a hst factory going there. You are well on your way to a completed quilt top.
That’s my favorite method. However, it looks like a storm of HST.
HST’s are a good addition to any quilt pattern. I like my Tucker Trimmer fro sizing my blocks. How do you find a Technical writer? Congrats on making a new Design.
Thanks! I got lucky with my editor, she is on a longarm forum where I participate in discussions.
I love to come back and see what you made of this. May be I am going to chain piece these hst too!!!
Thanks for linking up to Tips and Tutorials Tuesday! This is such a helpful tutorial!!! Don’t you just love Quiltalong.net??? Congrats on being featured there.
Wow now that’s interesting I’m new to quilting and I love it. This fast and easier way is going to work for me! Thanx
