How to create a masterpiece...

Ok so not so much of a masterpiece but creative work. I've had a vision for some time about a piece of work I want to create. It's going to take some time. I'm time poor but must do this. Art is a compulsion with me. I see in my head what I want to do, rarely make sketches and draw in space often with textiles. That's what I'm doing with my latest piece. If you can envision grey/blue slate. That's the colour of the wool I'm working with. In shape, a large column of knitted material reaching the ceiling, flooding across the floor and pooling over head. I want the feeling of encapsulation. Of being entrapped by this piece. I want it to unsettle or even scare. I want my viewers to step on the work, to feel the threads, and to be inspired to think of landscape/environment in which you become one with. Early stages. Lot of work. Completely absorbing.
