Hearts On A String
I started doing my 'hearts on a string' in pamphlet stitch junk journals a few years ago. I don't mind the look of the string ends at the center of my signatures, but this adds a finished look.
My favorite shape to use is the heart (but I sometimes use a butterfly or flower). I punch 4 of them in paper that matches the junk journal - 2 for each string. I glue the pairs back to back with the string sandwiched between them. It's such a simple but lovely detail!
