I was just looking at Pintrest and there are dozens of different looks for this pattern. Depending on the ages of your Girls Scouts may be a deciding factor in the colors. Include the girls in the decision making since this is their quilt. Great or good this will be their quilt and their quilting experience. You might be very surprised by them no matter their ages. My sister is a leader for a mixed aged group of girls. They all work on projects together but what ever is age appropriate for each girl is their input. It is amazing how many different quilts come out of this group.
