Fashion Designs.

I am still ploughing on with the fashion designs, probably totting up to around 700 now! Doing some sketchbook pages to make me design a bit free-er instead of just on a body. My designs are going to be fairly simple so I am not sure why I am struggling with it so much. On photoshop I'm trying to show the many layered prints and fabric on my designs by using the opacity tool. This is kind of working but it is very time consuming. Just thinking if I will work better printing my prints on tracing paper and playing a round with them that way.
