This is the hardest puzzle I have done so far. I had tried working on it once before and became frustrated, so I put it away. The 2nd time I decided to "cheat" by using the letters on the back of the puzzle, which made it do-able for me. I sorted the pieces by section and worked one section at a time. At times I even used the lettering to know which direction to place the pieces into the puzzle, to make it go faster. Even with doing all this, it was a very difficult puzzle for me to do. Maybe I'm more novice than I thought! If you're looking for a challenge, this one is for you.
