Half Square Triangles

Today is the first day of the Quiltmaker 100 Blocks Blog Tour!   Visit the other blogs listed today and tomorrow, come back to see my block and some options to use it!

In the meantime, here's a rundown on the different ways to make Half Square Triangles (HST).  I find that I use certain methods depending on the project I'm working on.  When making an HST, you typically need 2 different squares of fabric, 7/8" larger than the desired finished size.  So, to make a 2" finished HST, start with cutting two 2 7/8" squares.

1> The very simplest method is to simply cut a square into 2 triangles.  Sewing 2  triangles together make a HST!   This method is simple and fast.  However, working with the bias edges can sometimes be intimidating.  I would suggest using sizing or spray starch first to make things go more smoothly.

2>  The second, more popular method, is to mark the diagonal on the wrong side of a square of  fabric.  Layer two squares right sides together and sew 1/4" away from the marked line on both sides.  Cut on the marked line to get two HSTs.  This method is easy and simple but not as fast as the first.

3>  Using paper foundation is pretty popular.  There are several products in the market that work well, including software that allows you to print whatever size foundation you need.  This is such a great idea to make very precise HSTs.  However, tearing out the paper can be time-consuming.

4>  Use a ruler/template to cut or mark HST pieces.  For example, a lot of patterns require 2" finished HST squares using a 2 1/2" strip.  The best way to do this is to use special templates.  These methods are great when dealing with pre-cut strips.  

With any of these methods, one can always make oversized blocks that get trimmed down to exactly the size  needed.  So which way is your favorite?
