We finally figured the story out on this quilt. My oldest niece lived with my MIL & FIL for last 5 years of her life (as she had been kicked out of the house). My MIL was making this quilt for my niece's room. It was going to be her birthday present (reason why it was pretty much hid from everyone). She was working on the binding when my niece was killed in a car accident, this hit my MIL really bad so she just put the quilt up and never finished it.
It's finished now, and will go to someone in the family. I love the bright colors and I love the pattern. I also know, I will never have the patience to do this pattern, especially in a king size.
