The half square triangle unit is probably the most commonly used patch in a quilt block -- well it is second only to the square. It is made simply with two triangles, filling up half the square each -- hence the name. Take a quick look through this website, or in any quilting magazine, and you will start to notice that this half square triangle, regardless of its size, is present in more quilts than not.

The Best Friends quilt block is a seven patch block with lots of pieces. But, the good news is that none of the patches are difficult to make. In fact, only squares, rectangles and half square triangles -- the most commonly used patches -- are required in this block. For simpler construction (at least in my opinion), I choose to construct it as an uneven nine patch.
This block might look familiar to you, and you would be right. Below are links to other blocks that might be considered to be in the same family as Best Friends
The sample quilts illustrated are both constructed with an on point setting, but with just a few changes, they look very different. Your imagination is your only limitation.
