Creating this little pattern I was not able to choose the title.... Open MY Heart? open THE Heart??? open YOUR Heart!?!?
well, it's up to you to choose!
The way of knitting the heart makes it easy to fold ... and open...Inside you can even fix a small gilf such as a ring or necklace. You can write a poem or a message on a piece of paper, fold it and stick it onto the heart!
Anyway, Have a nice Valentine's Day!

PS. you can see "TVB" on one of the hearts... that's Italian and means "I love you"... such as "XO" is "English" ;)
