Great advice here!!!
I've done one, and I will say that the layout and photo is an iterative process - it can get better or worse the more you arrange the blocks. I stuck to the rue in the book about arranging the little pies only for straight of grain, but many people on the board have told me I could have done otherwise. (Perhaps if I had starched too, I could have done that). It gives you two more options for each assembled hex
Get a big enough design wall to see the whole thing.
And a 60 size rotary cutter with sharp blades!
Also I bought the ruler (why do I keep saying in various posts that I hate special rulers??? Every quilt I do is an exception to my hating them!) and it was a big help in cutting the triangles.
And get good quality fabric so you don't end up with misprints and variations which make it hard to line up perfectly.
And HAVE FUN!!! These quilts are lots of fun!
