Karen at Sew Many Ways has a a great tutorial for a heart bookmark that is perfect for Valentine’s Day.

These literally take minutes to cut and sew. The only change I made was to trim the seams and do some decorative top-stitching. I made these to enclose with my Valentines to the family this year.
Red fabric is good for Valentine’s Day but I couldn’t resist making one in an animal print for a daughter who loves it.
The back has a little pocket which slips over the bottom corner of a book page to keep your place.
To accompany the bookmark and to help explain how to use it, I looked through my collection of vintage cards for something with a book and came up with this one.
I scanned it and added the caption, “A Valentine Bookmark just for you”. The bookmark was slipped onto the bottom edge…
….and I wrote a personal message on the back of the card.
I think this will be a nice surprise as I continue the tradition of sending Valentines to special people.
This Valentine was sent to my mother by her first grade teacher in 1923
LILLIAN'S CUPBOARD 
Lillian, this is a great project and all of the recipients should be thrilled. I love your mother’s valentine.
I love your mom’s Valentine. It’s so amazing you still have it. My family has had so many disasters that I have practically nothing. I had seen the tutorial, but I love the way you extended it and added a fabulous card to it.
How cute and especially in your fabrics, the family will love them.
Dear Lillian, I just love this! Your talent inspires me.
Happy Valentine’s Day 🙂
