Once you sort this out it becomes very easy. Such a beautiful puzzle.
Unfortunately, the pieces are not all large format. My error for not verifying. I thought all 300 piece Sunsout puzzles were large format. This is the first Sunsout I purchased for my 90 yr old mother that isn't large format in over 50 puzzles! It is making it more challenging. It is a beautiful, festive puzzle!
Fun ,well done puzzle
