So I've fallen in love with bright solids and I love to make hexegon paper pieced flowers, but I hate to attach the flowers to each other because it gets too unwieldly. I came up with the idea to make a whole bunch of bright solid flowers and applique them on a solid piece of soft gray. Modern, quirky, bright. My niece has layed dibs to this one. I have a few options on how to do the final assembly and one consideration is it needs to be portable and granddaughter mess aroundable with. I also made different sized flowers using different sized hexegons.

Option 1: My original plan was to piece 44" wide fabric into a whole cloth and then applique the flowers all over.
Option 2: Just thought of this one, maybe cut huge squares like 30x30 and then have my niece arrange the flowers on each square to please her? This keeps the project portable longer, but does result in more seams.
Option 3: 12" blocks with one flower on each and then sash between? More time at the machine and more pieces, but still more portable than option 1.

I need to balance the portable piece with I want something that looks awesome when done. What are your thoughts?
