When it comes to choosing colors, I tend to look outside the box. I throw the color wheel out the window. I go with what I like even though, And it depends on what or who I am making a quilt for. I have chosen fabrics that people have said they wont go together and when they see the final quilt, it is like wow it does work.
Remember going outside the box can be hard for some but give it a try. Get your inspiration from everything you see. Look around you, you see color every where you look and can be an inspiration.
