I believe that it will change over time, go with what you think you want and then make adjustments as you find something that works for you. I do have several of my lines together, then Kids prints and Christmas together, all B&W together (that was the really easy one). I put the ones that read mostly tone on tone and solids into the color familys, then I have florals and Blenders. Will probably end up with one more category of those that dont' fit anywhere! I agree with your advice we have pulled our fabric out of the nooks and crannies and are still in the process of wrapping.
