You can see here what a half square triangle block looks like, a simple bringing together of two triangles into a square.  To make it less time consuming you can learn how to make 8 half square triangles at a time (my favorite method) or how to make 4 half square triangles at a time.


Using this traditional method you will be able to build upon it to make different styles of quilts. There are really so many possibilities and we will start with free tutorials here.
