After my first step of wet in wet painting and using plastic wrap to make a really cool design for the background, I then used an overhead projector to pencil a close-up drawing of daffodils in a vase over top.
This was not as easy as it sounds because it is very difficult to see where and what you're drawing! The creative part of this, though, is that you can pick and choose where you want to draw your flowers (or whatever subject). You're not limited to drawing the whole picture just as it is.
Does that make sense?
Once I completed that task, I began painting the flowers, beginning with the negative shapes (the background darks). A good way to do this is to think back to front and paint what is furthest away and move gradually forward, leaving your detail work until last. Easier said than done but well worth the effort!
Here is my finished piece. I'm calling it, "Daffodil Drama," not because it's a dramatic piece, but because I went through such drama to finish it!
