I don't have a king and can't comment on the size, however, I wanted to tell you that your quilt is amazing! I love all those little pieces and the final look when using lots of little pieces. I have been too intimidated to try something like that so far... I need more work on sewing a consistent 1/4 inch seam. I am in awe with quilters who can do it so well.
Thanks for sharing your photo.
