Half square triangles (HST) are a staple in the quilting world. I hear lots of quilters say they are afraid of them or that they take too long. Using the right method for your design can minimize the fear and time.
I use one of two methods for making my HSTs. Two at a time – is exactly what it sounds like, as is the Eight at time. There are other methods, but I steer clear of these as they leave the edges of the HST on the bias and I find I am not personally careful enough not to stretch my HSTs out of shape.
When determining the size of the HST needed for your quilt pattern begin with the UNFINISHED block size. Unfinished is defined as the size of the finished block + the seam allowance. Standard seam allowances for quilting are 1/4″ so that is what I am using here. If a finished block is 4″ then the unfinished block will be 4 1/2″ to include a 1/4″ seam allowance around the entire square. Once you know the size of the finished and unfinished HST, then determine the total number needed in a particular color combination. Use the two charts below to determine the size and number of fabric squares needed to make the desired number of HSTs.

I hope you found these charts helpful in your designing process. They don’t have to be scary or take up too much time. Remember to post your pictures on social media using #jitterywings or @jitterywings so I can keep up with the amazing work you are doing.
And, until next time…thanks for stopping by!
