Welcome to the Board! Great accomplishment, finishing a king sized quilt. I am sure only you see the mistakes.
My first bed sized quilt, a queen sized scrappy (2" squares) was called "Murphy's Millennium" made in 2000 with what was supposed to be 2000 squares (ha! My math didn't work). Need I say more? (Whatever could go wrong or whatever I could do wrong...yup...Murphy was actually an optimist when it came to this quilt! Just so you know, my daughter loves, loves, loves this quilt!)
Keep on quilting and check back here often...we all have our "Murphy" quilts.
