Oh, I think you should do it again! It's such a pretty quilt, and you did a wonderful job! :D :thumbup: :D :thumbup:
To make it easier next time, you could try machine basting the entire quilt first. Then, go back and do stitch in the ditch between all of your blocks. Now that the quilt is nice and stable, you will have more fun doing your pretty leaves and flowers! Just remove the basting stitches in each block as you decide to work on it...
I hope you do more quilts --- your color choices are great!
