As-salamu-alikum,

 I have learn from this chapter is about Denim and Jeans in details like definitions of these and twill. 

Now I can differentiate among Denim,Jeans and Twill. 

Besides there are more topic that covers the lecture and I have learnt so smoothly with help of our honourable Sir.

Alhamdulillah I have no problem to this chapter.
