Look at this most very useful colour wheel tool:
I would like to grab the front page to show you here but I can't figure out how to do that (yet).
So, just go and have a look, and have a play around with it.
You can work out all sorts of triad, tetrad, mono colour schemes.
ALL sorts of things!!!!
And thank you to Ansie at http://sonenskadu.blogspot.com/ who had this tucked away on her blog.
Back to making that quilt top for the give-away...
