Need Fill-in Ideas?
A few fill-in pointers to craft the perfect What I Love about You book:
1. If you're not a poet, or even a good speller, don't sweat it! Just be detailed and real.
2. Seemingly banal choices can be surprisingly effective. ('I love your nose').
3. Write out your fill-ins on a separate piece of paper first. It's less pressure.
4. If you're stuck, cross out and rewrite the prompts to make them work for you.
- Don't overthink it
- Don't judge
- Just relax

My Review of the Knock Knock What I Love about You Book⭐️ Robin ⭐️
About the author

Knock Knock is a maker of products that bring wit, heart, productivity (and occasional light profanity) to everyday life. Their pads, planners, journals, and books help people accomplish their goals, express their feelings, and laugh at the absurdity of modern existence. Satisfy all your witty needs at knockknockstuff.com.
Knock Knock lives by (at least) two mottos: “We Put the Fun in Functional” and “Make a List—You’ll Feel Better.” They consider list-making and laughter to be essential forms of self-care. (And, obvs, they love mottos.)
Knock Knock was founded in 2002 by Jen Bilik, and in 2018 they joined forces with Em & Friends (formerly known as Emily McDowell & Friends). In 2022 their small-but-mighty team was thrilled to become a part of the Union Square & Co. family. We’re super-excited about what’s to come. (Hint: it’ll probably involve paper and some sweary words.)
Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

- Reviewed in the United States on February 11, 2024I recently gifted my boyfriend the Knock Knock What I Love about You Book for Valentine's Day, and let me tell you, it was a hit! What makes this book so special is its personal touch – you have the opportunity to fill in the blanks with your own sentiments and memories, creating a truly unique and heartfelt gift for your significant other.
My boyfriend absolutely adored flipping through the pages and reading all the little reasons why I love him. It's like a love letter in book form, filled with inside jokes, shared experiences, and heartfelt declarations of affection. Seeing his smile grow with each page turn made my heart swell with joy. What sets this book apart from other gifts is its timeless quality. It's not just something to be enjoyed in the moment; it's a keepsake that can be treasured for years to come. Whether displayed on a bookshelf or tucked away in a drawer, it serves as a beautiful reminder of the love and connection shared between two people.
The best part? It's incredibly easy to personalize. The prompts are simple yet meaningful, allowing you to express your love in your own words. And because it's a book, it's something that can be revisited time and time again, serving as a source of comfort and reassurance, especially during those moments when words may fail us.
The Knock Knock What I Love about You Book is more than just a gift; it's a celebration of love, laughter, and all the little things that make relationships special. If you're looking for a thoughtful and enduring way to express your affection, look no further – this book is a true gem.
