In the tutorial section there is a lesson on color. I don't have a natural eye for color which is why I researched it and wrote the tutorial.
How to learn to choose colors is a lot more complex than it would seem isn't it?
When I first started I thought I could just choose colors and patterns that I liked and that would work. But having looked at quilts that are done by others I've noticed that color and pattern choices can make a huge difference.
This is what I am doing now. I have an overhead projector so I take a picture of the completed quilt usually from the front of the pattern. I make it large enough that I can cut out the pieces leaving enough paper to hold the pattern together. A template, then I take that shopping with me. It allows me to insert the fabrics where they will go so I can get an idea of how the colors work together.
Of course I still have to pay attention to the color wheel and other considerations.
