I love where you placed the blocks. Very nice. But then I saw that your grouping of 3D items seem to have the shadow at the back and the single placed blocks all had the shadow in the front. Personally, I think it will make a great conversation piece and make everyone really look at the quilt. Oops....looked at it again. It's only the blues that have the shadow in a different orientation. Regardless....I love it! If it were mine, I wouldn't change a thing.
What pattern are you using for the grouping of blocks?
