Having eternally a limited budget for such projects, I used fabric scraps I had available (buying only enough for the blue-grey border, and the backing), and used the dark red as center stripe on all the blocks to visually tie it all together..... and, of course, arranged similar-colored blocks in sorta diagonal stripes.
I find myself attracted to doing various "scrappy" quilt designs, tho I never quite pull of a proper "crazy quilt".... in spite of best efforts, I always end up with "scrappy-contained-chaos".

I absolutely love how the "Scrappy Green Lattice" turned out![/quote]
The quilt in your avatar is amazing.
Do you have a larger photo of it I'd love to see the details and colors.
