Conchalea - I hope you get a chance to try the design with your own colors. I have seen a few examples where modern colors and fabrics have been used and the design really pops giving a crisper look. When I saw the design I liked the concept using the different triangles and rearranging them into different blocks.
I am going to skip Block #6 right now and move on to #7. I ordered some fabric for #6 so that I would have a bit more variance for my "light" and "medium" values. Should arrive next week - hope they work out ok - if not I will have to rethink my fabric placement.
