Sabine at http://trytobead.com/ has this lovely pattern, which is free on her site.
She offers many versions of how to lay out your colors to get different effects.
I like mine, created with older stain glass windows in mind- the type of windows where the colors have softened over time.
What look could you create with this pattern?
Do check out her other patterns....they are all well-written and easy to follow, with drawings, photos and wordage.
