Creating Pattern Repeats

I love fabric designs-- but had no idea how one worked out a repeating pattern (like this recent fave, called Chiang Mai Dragon, by Schumacher). So I love the simplicity of this tutorial, over on Design Sponge. (sorry, can't for the life of me remember whose link sent me over to it.)

I've also enjoying gaining insight into the process of the pattern designer over at the blog of Tula Pink.
