Your quilt is beautiful. Finish it however you think will make you the happiest. If you're mentally done with the quilt, make do, or have a couple of blocks that are different. If it's a quilt that will hang out at your house and bother you, make a couple more blocks.
This is one of the first quilts that caught my eye when I first started quilting and first found The Quilting Board. At one time, I purchased fabrics to make it, but then used them for projects to teach my children to sew. Now I have my sights on something really challenging ~~ like a Judy Neimeyer quilt. I may have lost my mind entirely.
