I have added a second skein of the Ruby color "Jewel Box" yarn
click on to enlarge:
The one at the left is kind of like your "Chambray" yarns.
The "Unger" is: 80% Acetate--20% Polyester---Made in Italy and is a stiffer yarn. I think crape when I look at the Unger Yarn.
I would say that these two would be more for pretty trims on purses and such. Both have a shinny strand running through them,,,would make for a lacy look.
The one to the back right is Chenille.
