Need Fill-in Ideas?
A few fill-in pointers to craft the perfect Why I Love my Sister book and best sister gift she'll receive this year:
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
- She is going to love it

- Reviewed in the United States on December 6, 2018I love this- such a thoughtful gift. I bought several of these for my brother in law, sister, mom and dad for Cmas. I wish the questions were listed in the product description but because they're not, I'm posting them here, hopefully to help others! It is nice to draft something before writing them in- becuase some of the questions are similar. Someone did it on another review of one of the other books and I found it so helpful so I'm doing it here...

4.0 out of 5 stars A decent gift
The size is small, but it makes you revive all your special memories
- Cindy SpowartReviewed in Canada on July 20, 2023
5.0 out of 5 stars Priceless
My daughter started a family tradition w/ these great hard covered little books. She bought me the Mom one. If you're going for serious, it's thought provoking to come up w/ the answers. They can be a beautiful keepsake that doesn't take up much room at all. We've since done the daughter, son, sister and brother ones. I bought one for my sister for her 60th birthday. She said that she had to keep stopping, while reading, as happy tears flowed from her eyes. I plan to buy one for my brother-in-law for Christmas. Also, depending on the ages of the people they're given to, they don't have to be a one-off gift. You can update them every 5 or 10 years. I bought another brand one time and was SO disappointed I wouldn't use them. These are definitely the GOAT. Highly recommend for some serious heart string pulling. I also love the family tradition part my daughter started. Great for dear friends as well. Great binding, super hard cover and quality paper to write on. Great price for a superior product.

5.0 out of 5 stars Meaningful gift
This little book makes for a perfect meaningful and affordable gift for a sister. The fill in questions inside are 50. Some of them got me thinking a lot about old memories I shared with my sister. This is truly a great little symbol of appreciation.
