Half Square Triangles Quilt techniques

I found versions of this quilt pattern all over the internet.  Good reason, it looks good in almost any color and is relatively easy to make. 
​The first video, from Shabby Fabrics uses 5 inch charms.  She also gives some good tips on useful tools and rulers.  The half-square-triangles are made one at a time, but she does chain piece them to save time.

Here is a link for a list of the FREE patterns that Shabby Fabrics offers.  Scroll down to the Blitzen Quilt.

This video from Sew Very Easy uses fat quarters to make 8 half-square-triangles at a time.
