Thank you. I have that catalog. I will look at that picture.

They could be sewn together to make a square and do a four patch. I am going to post a pic of the scrappy quilt I finished last Sunday evening. I made that way with larger triangles the same color to make a square, then alternated them with the other and strips sewn together.
Two triangles make a square, just match the colors or use different ones together.

Lots of patterns to choose from:
