Fashion illustration

Illustration has always been a process of fashion design that is quite essential by todays standard. And i find it very useful and also professional, especially when the need to present portfolio arises. I did an intensive course at LARC and made sure i went through the art of fashion illustration, sketching the conventional way, but now - Thank God for technology. I got hold of the book 'From pencil to Pen tool' By Jemi Armstrong to learn this. You will require Photoshop, pentool etc.
I think its a very valuable skill to have inorder to develop one of a-kind design. I am sure any fashion design student or ever dressmaker would agree with me that sometimes you have this mage in your head, but i guarantee that this is such an easier way to get it on paper or to convey it. I am just learning it anyway - but i am able to apply my moodboard or generate my themes inline with the designs. Will post up what i come up with in future!
