I made one with 2 shades of purple, 2 shades of green, and a funny white pattern strip. dark green, lighter green, white, lighter green, dark green strips, all going the same direction. did the same with purple, dk purple, lighter purple, white, lighter purple, dark purple, all going the opposite direction as the green. I almost cried when it left, cause it was so gorgeous. it looked like a basket weave, and the dark and lights were all the same intensity. there really is no right or wrong way to do it as long as you like the outcome. try some different combinations and go with it......
