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.
This video from Sew Very Easy uses fat quarters to make 8 half-square-triangles at a time.
This video by Jenny Doan at Missouri Star Quilt Company uses 10-inch Layer cake and makes half-square triangles 4 at a time.
