Have some training in Interior Design or architecture major.

I'm nothing but a curious little bug in the great cosmos, but willing & eager to learn. You said you graduated from 'Fine Arts'.........being ignorant of such matters, what did you learn there ? Can the knowledge learnt there be brought forward into interior design ? That is, is further schooling even necessary ?

Fine Arts is different domain of interior design, I graduated from Fine arts-painting department - from Egypt.
In my point of view, this department is full of options to learn many things and theories, and the most important thing that I learnt is "all about colors"
Colors from many sides .. and I think that I'm talent in colors. and at the psychological side the colors is important and has true effects on the people.
And it's ok and not difficult to remodel or to design a house but I need to learn, how can I put my design in action, I need to learn some techniques, and to have info about the different materials.
