Rff1010 -- the color placement as in dark/neutral is probably more important than the actual fabrics, especially if your fabrics are close in value/scale. When Bonnie specifies groups of whatever, there is generally a step where we put those units together in some way usually as blocks but not always to fill out an overall or secondary pattern. Sometimes we are given directions just to help the "mystery" part. The reality is that one block a little not like the others will probably get lost in the overall project.
I'd play with your pieces in various ways, combining them into various HST shapes like broken dishes, or pinwheels and see how you feel about them. Not too late to make an additional group if you aren't happy, what's a couple of extra HST after all??
I still think these are awfully big units for a Bonnie Hunter project and that maybe we will cut them in half and recombine them later.
