Update: Overwhelmed on expanding this WIP

The top is finally completed, and ready for quilting. I wanted to thank everyone for the comments and suggestions on how to expand this from the small top I've had completed for ages (photo 1) to a queen-sized-plus quilt (photo 2) for a wedding gift. For those who saw and commented on my original post, I went with Option 3. I'm still not 100% convinced that I couldn't have gotten away with Option 4, but it's all ready to go and I'm feeling pretty good about it. I really appreciated the support from this community.
